I just verify why servers does not ping each other and we are done! New here? Issue the show crypto ipsec sa command on R1. By default, the Cisco ASA 5505 firewall denies the traffic entering the outside interface if no explicit ACL has been defined to allow the traffic. In the following command, "inside" is our local interface, 192.168.1.100 is the local IP we're testing traffic from, 12345 is the source port (it can be anything you choose), and 192.168.2.100 is the remote IP we're trying to reach. 7/ Finally, lets verify that the tunnel is up and running using the below commands: Output of Phase 2 being successful is shown below, configuration is incomplete This interesting traffic will trigger the IPsec VPN to be implemented when there is traffic between the R1 to R3 LANs. For example when you configure IPsec on a router, you use an access-list to tell the router what data to protect. Did you change you setup ? Please, run the file again and youll be able to ping server to server. Theres no command as far as I know. 2/ Setup Phase 1 of the IPSec Tunnel.

This is where the IKE negotiation takes place. Thank you fo your feedback. I have setup a more complex network structure, likely more representative of the real world, the internet requires multiple hops and the addition of NAT at both ends means you cant naturally route into the opposing network. Does the isakmp keep retrying itself or can i manually trigger a retry? We will be using 256 bit AES encryption with hash message authentication code providing confidentiality, integrity and authentication. Let me point to you where did you fail: -R1 should have a static route like that ip route 192.168.2.0 255.255.255.0 10.1.1.2, -R2 should have a static route like that ip route 192.168.1.0 255.255.255.0 10.1.1.1.
