Hi. Currently we have a 1450 appliance in a serviced office. We are going to swap it out for a 4000 appliance. We have 1 internal interface that's the default gateway of the PCs. Its IP is 10.10.10.1. Looking at the routing table, any traffic for the subnet 10.10.10.0/24 is forwarded to the same interface (LAN1; IP 10.10.10.1)
On the full version of Gaia I know if I put in the next hop as 10.10.10.1 I will get an error saying that the IP is already taken by the FW interface. I believe all I need to do is to specify the next hop as an interface and the routing should work (I don't know the IP of the switch downstream). I don't have a means of testing until the migration is in progress - am I thinking along the right lines with this?
