[kasser]

Hi all, A working VPN is now not working, i think the problem is ISAKMP setting mismatch but the other side deny this. Below is the error I get can someone shed some more light on this.

I have checked all settings and renetered the settings but still getting the same error. not sure why this is happening all of a sudden. From other checks the only one that I am concerned about is show crypto ipsec sa command this doesnt come up with anything and im not sure why? can some one help me please?

Can you post the configs of both ends? (Take out passwords and mask the middle 2 octets of the public IPs.)

What type of firewall is on the other end? Cisco, Checkpoint?
Can you post a "debug crypto isakmp". Need to see the connection setup/negotiation.
