Check the IP-* mini HOWTOs Since I don't know enough about that, I would do it like this: If you have apache listening on port 80, you can configure it to redirect all incomming queries to another host. To route e-mail to another host, I would setup an MX record on your nameservers pointing to the host you want your e-mails to be redirected to.

It allows you to do exactly what you described above. (at least for tcp) Check http://www.tis.com/prodserv/fwtk/readme.html for further infos. btw: the fwtk is usually within a linux distribution (eg. Suse,Debian,Slackware) Cheers, Philipp Nyffenegger --- ASCOM AG Tel. G. : +41 (0)31 999 34 96 NISI Intranet/Internet Tel. P. : +41 (0)31 981 25 81 Belpstrasse 37 Tel.
