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.
