Hi all,

I got a problem with a Lan-2-Lan connection from my Active/standby 5510's with Sec Plus License

the config on the firewall is this

but I still get errors such as the Log File below.

As soon as I let it build the tunnel all works fine but then a few seconds later it all falls down :-(

What am I missing ?

Please help.

Hi

Since you have not given the full config, i think there is an issue with your peer IP's and also crypto ACL (as per logs).

From your ASA config, the set peer is 1.1.1.1 but from LOG it shows as 11.11.11.11 and pls check the crypto acl also.

here is a little more info than before....

As before the Phase 1 and Phase 2 work - data passes over the tunnel but then all just drops and what I see in the log is what you have here in the above attachment.....
