I'm trying to connect to a proxy running in Irssi which I am forced to run on a high port, 103239. I had this working on my old install, but after doing a fresh install on this system I can no longer connect. mIRC seems to ignore the port number and fall back the the default 6667 port. What's the trick to making this work?

103239 is not a valid port number; the highest possible port number allowed by the TCP protocol is 65535. If irssi proxy accepts this port number, it is probably taking it modulo 65536, which results in port number 37703. So you could try connecting to that port with mIRC. Or specify a valid port number in the first place, of course.

That was it. I booted my old install and I see that's what it had done. Even though it was set at 103239 mIRC was connecting to 37703.

I wonder if something changed where mIRC used to do that same modulo, and that is no longer the case. I don't remember ever figuring this out before...

Thanks for the help!
