When using -dedicated, how do I specify the network adapter?

e.g. I have some virtual adapter and a wifi adapter on different networks, and when i hosted a local server and tried to join it, i think bitfighter used my virtual ethernet adapter, because it worked after turning that off and it looked like they were on the wrong network (wifi is 192.160.0.0/24 and bitfighter was hosting/playing on 192.168.56.0/20)

a workaround was to disable all adapters besides my wifi on every computer, then i could play bitfighter on my local LAN

but it'd be better if i could specify the network to use
