[QUOTE="Raz0rEdge, post: 1819511, member: 110816"] The way you "force" an app to use one interface over the other is by choosing to access a resource available on that interface only. However, with dual subnets the thing that will usually cause you grief is the default gateway. Each of your subnets also has a gateway of its own. But the default gateway is where things go if it can't be directly routed. I would suggest that your default gateway be the Internet facing IP address and interface so that your DNS stuff works like it should. For your internal (2.x) interface, I would suggest you direct requests using specific IP addresses. You can create entires in the /etc/hosts file to give those devices nice names so you don't have to remember IP addresses. This will prevent traffic from going down the default gateway (Internet facing) interface. [/QUOTE]
