Hi Everyone... I have a strange issue that I have been struggling with for the past 2 weeks. I have a Cisco asa 5505 running 9.1.6 (I updated to latest version to see if it fixed issue, but it did not). I am trying to setup a site to site VPN tunnel to a Sonic wall TZ300. I can get the tunnel up without issue, and the tunnel stays up. When I try to access the network behind the sonic wall (192.168.10.0/24), I get no response.
On the ASA, I go to monitoring -> VPN and see the session connected. I see Bytes TX with a non-zero value, but Rx stays at Zero. I double click the tunnel and see IPsec with my local network 10.10.1.0/24 and the remote network (192.168.10.0/24).
I go to the Sonicwall and see and see the tunnel with bytes in and bytes out. So it receives the traffic and looks to be replying.
I have my nat exemptions configure.
Any ideas? or hints? I really tried to figure this out on my own, but I am stumped.
