Hi

I would like to run some mail servers and web servers behind a firewall

how would I get the firewall machine accept incomming request for the
servers behind ....

would I need an IP for each server behind the firewall?

for example...

port 25 on 203.166.226.1 for mail1.mydomain.com
port 25 on 203.166.226.2 for mail2.mydomain.com
port 80 on 203.166.226.1 for www.mydomain.com

so on and so forth....

is it just a case of writing the right rules into the firewall or another
program to do this?

also whats best practise for running servers behind firewalls/proxies in
FreeBSD ?

I'd also like to have the firewall machine do NAT, I know how to do this
with IPFW and natd... would this affect the things I wanted to do?

thanks for the pointers and ideas
