Using a box with two interfaces (namely, one of them being a wireless interface) with each one connected to a different physical network.
Identifying applications locally running on the box by their source port, I want to route the packets from specific applications through one or the other interface.
The idea is that
- using a ruleset, each (or some) applications are routed through the non-default interface from the moment they start
- when the default (eth0) interface goes down, the specific applications are routed through the other interface
While, hopefully, keeping the applications' connection live.
yeah, I know things look grim.
My best guess is that it's gonna have to be a new custom filter for netfilter, but I dont know what I *could* do with that.
Any help is appreciated
