We have a SonicWall 2040 Pro and we are having issues with setting up interface X3. I previously set up interface X2 as a DMZ with no problems, but X3 is giving me a headache.
My intent is to set up X3 and plug a WAP into it so that I can set up separate rules for wireless accessing the LAN. The WAP sets up ok, and DHCP passes fromt he Sonicwall to the WAP and also through the WAP to the wireless clients. They receive the IP address and DNS settings OK. Wireless clients are able to communicate with the LAN, but not the internet.
I double checked, and the rules are in place to allow the traffic to the internet, so at first I thought it was DNS, but I could not access www.google.com
(one of Google's IPs). Futher, NSlookup of the google.com IPs works to our internal DNS server (primary) but NOT to the external DNS server (secondary).
It is like X3 is getting blocked from just the internet... I checked the Sonicwall logs and nothing shows up - no rule appears to be firing that might be blocking the packets.
