I'm almost at the end of my tether and hoping someone can help.
My scenario is this, I have two sites, one with a Cisco ASA and one with a Sonicwall TZ300. I am trying to establish a Site to Site VPN between the two. The VPN comes up, but the sites cannot communicate.
During my testing I tried connecting to another site using a Fortigate 200B. The Site to Site VPN from the Fortigate to the Cisco comes up and I can communicate across the link. However, with the Sonicwall, again the VPN comes up, but no communication. I have therefore come to the conclusion that the issue is with the Sonicwall.
I can see the traffic send stats increasing when attempting to communicate, but nothing coming in. Likewise with the Sonicwall, it will send but not receive (according to the logs).
I have tried creating the VPN with the Wizard and manually.
- There...
