We have two internal interfaces X3 and X4 on a SonicWall Pro 3060, firmare 3.1.0.2.
Addressing for X3 is 192.168.0.1/255.255.240.0, and addressing for X4 is 192.168.100.1/255.255.240.0. Each interface is connected to it's own switch. Recently it was decided that devices on X3 should be able to talk to X4.
I'm not a networking pro, and I ~~know~~ think that routes should be set up to allow this. Can anyone give any insight into best practice and how to execute this?
