Hi,

 

If I got you correctly, you are not able to pass traffic across the VPN tunnel. Please correct me if I am wrong.  The problem lies on the ASA where encrypt is "0". There can be several reasons for packets not getting encrypted. They are:

1. Nat Exempt is not applied on the ASA or any other NAT rule is redirecting it through any other interface.

2. Return traffic from the host is not coming back to the ASA so that it can get encrypted. To verify this, apply capture on inside interface so as to see outgoing and incoming packets.

3. Traffic is getting encrypted and is entering any other tunnel.

4. Traffic is getting dropped by the ASA because of any conflicting rule.

 

Please focus on these issues anf it does not help then share the configuration and I will be in better position to help you.

Hey John, Actually it was working perfect in past, not sure what goes wrong.

Yes crypto ACL's are mirrored. Tunnel is Up and traffic passing on one subnet but the other is giving problem. Anyways the problem has been solved by removing the VPN configuration and reconfigured, Also have changed the pre-shared key.

Thank you guys for all the valuable comments and support. smiley
