I have a Dell Sonicwall NSA 220. I have X0 setup as a LAN of 192.168.1.x and another on X2 of 192.168.253.X. I want to be able to have both LAN's to see each other. I already have "Allow Interface Trust" enabled under "Network/Zones" enabled. I'm still not able to ping between the LAN segments. Please help, thank you.
