IPSec Site-to-Site VPNs w/Static Virtual Tunnel Interfaces (SVTI): IKEv1 & IKEv2
 
02:36:29
The following video tutorial takes a deep dive into Static Virtual Tunnel Interface (SVTI) interfaces along with both IKEv1 and IKEv2. We explore all the similarities and differences between the configuration and operation of SVTIs with IKEv1 and IKEv2. The IKEv1 scenario connects two offices together over the Internet and the IKEv2 scenario connects up two offices over an MPLS L3 VPN architecture. Thanks to some typos we also get to troubleshoot what happens when you use a route-map with the wrong name, what happens when a route is learned via eBGP and you want it to be learned via EIGRP (AD concerns!), and when you enter in IP addresses wrong (good troubleshooting)! In each scenario the configuration for either EIGRP or OSPF is done so you can see how to run either routing protocol over your SVTI. The next video will show the same thing, but with crypto-maps! Enjoy!

In this video we take a look at the configuration and application of GRE over IPSec site-to-site tunnels between Cisco routers. Throughout this video we compare and contrast the "crypto map" approach to the "SVTI" approach and some of the background of crytpo maps. We also configure OSPF as our dynamic routing protocol of choice over our point-to-point GRE tunnel. Hope you enjoy!!!

GNS3 Topology: https://goo.gl/udfNPL Get the VPN Config Generator and all my videos as part of a subscription here: https://goo.gl/mJMZGW Cisco documentation: https://goo.gl/hjmdFR For lots more content, visit http://www.davidbombal.com - learn about GNS3, CCNA, Packet Tracer, Python, Ansible and much, much more. IPsec Overview: A secure network starts with a strong security policy that defines the freedom of access to information and dictates the deployment of security in the network. Cisco Systems offers many technology solutions for building a custom security solution for Internet, extranet, intranet, and remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

IPsec Overview: A secure network starts with a strong security policy that defines the freedom of access to information and dictates the deployment of security in the network. Cisco Systems offers many technology solutions for building a custom security solution for Internet, extranet, intranet, and remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

IPsec Overview: A secure network starts with a strong security policy that defines the freedom of access to information and dictates the deployment of security in the network. Cisco Systems offers many technology solutions for building a custom security solution for Internet, extranet, intranet, and remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

UMUC - CMIT 454 - CCNA Security - Spring 2018 - PT 8.4.1.2 Site-to-Site IPSec VPN - Week #6
 
01:29:51
In this comprehensive 'techtorial' on configuring Site-to-Site IPSec VPNs on Cisco routers with crypto maps we dive into how to secure our data communications. We start with a brief introduction to setting up Site-to-Site VPNs with crypto maps, talk about the use of GRE to support multicast/broadcast for routing protocols, and then discuss the current implementation of point-to-point VPNs using Static Virtual Tunnel Interfaces (SVTI). We go over the semantics of the IKE and ISAKMP Phase 1 and 2 settings, transform sets, tunnel mode vs. transport mode, and end things with a brief discussion of DMVPN and how it fits into the overall architecture of data security. This is all done through the lens of Cisco Networking Academy's CCNA Security v2.0 Packet Tracer activity 8.4.1.2 Enjoy!!!

Static Cisco VTI VPN with FortiGate 5.x Guide
 
10:45
In this short video I show a brief overview of the step by step requirements to create a VPN between a Cisco IOS using VTI and FortiGate 5.2.x track using 0.0.0.0/0.0.0.0 Quick mode selectors (Single P2) Reason to configure your Cisco with this type of VPN: • Simplifies management---Customers can use the Cisco IOS® Software virtual tunnel constructs to configure an IPSec virtual tunnel interface, thus simplifying VPN configuration complexity, which translates into reduced costs because the need for local IT support is minimized. In addition, existing management applications that can monitor interfaces can be used for monitoring purposes. • Supports multicast encryption---Customers can use the Cisco IOS Software IPSec VTIs to transfer the multicast traffic, control traffic, or data traffic---for example, many voice and video applications---from one site to another securely. • Provides a routable interface---Cisco IOS Software IPSec VTIs can support all types of IP routing protocols. Customers can use these VTI capabilities to connect larger office environments---for example, a branch office, complete with a private branch exchange (PBX) extension. • Improves scaling---IPSec VTIs need fewer established security associations to cover different types of traffic, both unicast and multicast, thus enabling improved scaling. • Offers flexibility in defining features---An IPSec VTI is an encapsulation within its own interface. This offers flexibility of defining features to run on either the physical or the IPSec interface.
