ASA5505 Dynamic L2L Traffic Won't Pass - Phase 2 Problem

Steven Tolzmann

                   Hi all,

I have a Cisco ASA5505 I am setting up for a new site, and I am having trouble getting VPN Traffic to pass, despite "sh isa sa" showing the tunnel up. Internet traffic passes fine. I am also able to ping the remote endpoint. The Endpoint ASA is the central ASA for our Company Network, everything is set up in a Hub & Spoke topology. All other nodes on the network are working perfectly.

I based this new ASA config off another working Dynamic Wan ASA5505... I have checked this config a lot and can't find any problems, but was wondering if anyone sees anything wrong?? Here is my CLI outputs:

xxxxx-ASA5505# sh run

Okay, well it just started randomly working.

ping inside 192.168.9.x

did not work.

However when I connected a host to the ASA and tried ping in windows, traffic passed the VPN just fine.

Weird.
