C socket question - Binding twice on the same address/port

HI,

I'm working on a routing daemon for IRC servers and have a question.I binded the routing daemon's port once for receiving incoming messages. But I want to bind the same port again when sending outgoing messages so that neighbouring daemons can tell it's coming from this specific daemon. I'm getting a bind failure on the second try.Am I just doing it wrong or is there a way to force it to allow me to bind?

Any help will be apprecited.

I didn't find the right solution from the Internet.
