Crypto isakmp not available in gns3

Grab the GNS3. First of we enter config mode then enable isakmp, although by default it is enabled this probably wont be needed.

The policy number is quite important. When the router tries to negotiate an acceptable phase one policy it always starts with the policy closest to 1 then work up in order until a negotiation is successful using 10 leaves some room for growth if needed.

Now we configure the authentication method. For simplicity we'll use PSK at the moment. I'll do another post soon to explain the other options.

Now we configure the encryption algorithm we want to use. Group 5 isnt supported on all versions of IOS! Lifetime is the time in seconds the Security Association SA. Since we configured pre-shared key we need to configure the key on a per host basis in main config mode. Just to emphasize dead peer detection DPD we set it to send keepalives every 10s then every 2s if a keepalive fails. Sent on demand rather than periodically like we have configured is the default.

Various other options are. We configure the IP or hostname of the opposite end of the tunnel. Configure the "interesting" traffic with the match command then finally configure the transform set to be used. Verify with show crypto map. Apply the configured crypto map to the outgoing interface. We need the static route to point to the router at the other end of the VPN tunnel. Here is the configuration of all three routers.

This packet arrives at R4. R4 needs to route it, checks its routing table and sees a default route to R2. We can verify this with show ip route. The crypto map is configured for peer R1, you use ESP and you have a matching access-list so this packet should get encrypted. We can verify this with show crypto ipsec sa.

The outer IP header now looks like:. R1 receives an encrypted packet. R4 is a valid peer, It de-encapsulates the packet and ends up with the original IP packet:.

It checks the destination, R1 has a default route towards R2. There is also a crypto map on the outgoing interface.

You have a peer and a matching access-list in your crypto-map. You can check a single peer with show crypto ipsec sa peer R3 receives the encrypted packet, R1 is a valid peer so it de-encapsules the packet. We end up with the original packet:.

That would be a bug in GNS3, try to save the file, close it and reopen it. As you can see from the output on R2, the encrypted and decrypted packets are equal, meaning that the tunnel is working properly. I would not agree with Lionel, because phase 2 tunnel would not be up if phase 1 tunnel is down. Your configs work fine in gns3 here, all commands showing output pinging pc to pc Aref, that seems to have fixed the problem.

It's working as it should be now. Thanks for the tip. Thanks to everyone for the additional info. That helps as well. Trying to make this all sink in now.
