Currently the only way to change which network adapter mIRC will use to connect is in Options > Connect > Options > Advanced. The ability to change this on-the-fly, per server (and not changing the 'default' bind ip) would make things a little faster, easier, and more accessible to scripts.

If seperate dcc port ranges could be specified dependant on what interface ip the /dcc send|chat is sent from, users would not have to constantly switch the dcc port range to conform with the port forwarding set up for each individual ip.

[note: I'm aware this *sort of* conflicts with the -d description field for the /server command - despite the fact that -d should only apply when used with /server -a. I used -d to stay uniform with the various /sock... -d commands]
