Hi AL, What you're trying to do is certainly possible. Taking a guess as to what your setup might be, you'll need need a natd.conf (or whatever you decide to call it) that looks something like this: ----------------------------------- interface rl0 redirect_port tcp 192.168.1.200:25 25 redirect_port tcp 192.168.1.201:80 80 redirect_port tcp 192.168.1.201:443 443 ----------------------------------- The first line is the interface name (realtek in this case). The mail server is on 192.168.1.200 and the web server is on 201. Pretty simple. I assume you've got natd (and dhcpd) working anyway, so you've done the hard bit. I guess you just need confirmation that it will definitely do what you want. Regards, Frank.
