Ok so we just changed the configuration of our work network to having VLANs and added a layer 3 switch to our network. Now when we plug the watchguard XTM 5 back up to the network it doesn't work. Tried some different configurations on it and it still didn't work. Originally it was plugged up with port 0 going to the router that was receiving signal from outside and port 1 was connected to a distribution switch. Now it is plugged up to the same router and the next step in our network now is the layer 3 switch which is now doing most of our routing functions. So we tried the same configuration just changing the connection to the layer 3 and it didn't work, any ideas?
