I am trying to setup a VPN tunnel between a Cisco ASA 5505 (Version 8.2) and Sonicwall TZ200. I got tunnel up and going and I am able to ping the Cisco ASA internal IP from the Sonicwall LAN but nothing else works. When I try to ping a host behind the Cisco ASA from the Sonicwall LAN I get the following message "Asymmetric NAT rules matched for forward and reverse flows; ... denied due to NAT reverse path failures"
Googling the above error shows issues with version 8.3 and later which looked like the nat commands were changed but the ASA I am working on is still on 8.2 and the common issue is not adding a NAT exemption. I have double-triple checked that I did add a NAT exception rule from the hosts on the cisco network to the hosts on the Sonicwall network. Seems like I have hit a road block so any help would be appreciated. Thanks
