I would like my IRC client to only use a WiFi connection and all other programs to use WiFi or wired connections. This is because every time I plug in my Ethernet cable my IRC client automatically reconnects over wired, and then when I disconnect the cable it reconnects me on wireless.
So now I have multiple users logged into IRC.
Can I force an app to use a certain connection over the others? I like having the wired connection as the primary connection over wireless, because I do a lot of uploading and downloading and the NIC card gets hot sometimes. I guess I should of stated I'm using a MacBook Pro.

Add a static route for your irc server. For example I have 2 interfaces: wired (en0) and WiFi (en1) of which the wired one is the default. So if I get a route to a server, it will go through the default interface (see interface line in output) :
But if I add a static route through the WiFi interface en1 however :
The route will disappear every time you reboot. To make it permanent you would have to create a script launched as a startup item or a custom launchd script.
