There is a little program which comes with INN which can do this (backends/rcompress.c). It can be altered to forward connections to any server on any port. I've used it to forward NNTP connections past a firewall, using tcp_wrapper in inetd to control access. -- Scott Barker Linux Consultant [EMAIL PROTECTED] http://www.cuug.ab.ca:8001/~barkers/ (under construction) [ I try to reply to all e-mail within 5 days.
