The simple steps you could take to start with is to check if the configured ACLs are allowing the required truffic through and check that "isakmp nat-traversal" has not been disabled if NAT is used that is, NAT-T is on by default.

Can you ping the peer?

Hi Victor,

The acl is permit any any so it should be fine. I am not able to ping the peer.

It looks like phase1 is completed and the connection is broken at phase2.

You may need to paste the configs from both ends of the connection on the forum. It will be a lot easier for everyone envolved to try to resolve the problem.
