To do this, I have setup an ipchains rule as follows: Silly question, but why are you trying to use a different port on the second IP? IIRC, since this is a different IP (even though it is aliased), it has it's own set of ports thus 1720 isn't used on eth0:0. Someone please correct me if I'm wrong here. However, I use aliases myself and haven't run into a port conflict of any kind. Jamin W.
