You certainly can.

When in m0n0wall, go to the 'Firewall' section, then 'NAT'.  Here you 
can create new rules that specify that certain ports map to any internal 
address that you like.  Just be sure to add a firewall rule to allow 
this (it has an option at the bottom when creating a new rule to 
auto-add a firewall rule).  Otherwise you will have a port map to where 
you want it to, but the firewall will block it.

You can map any port to any IP on the LAN for example, if you had one 
machine that did e-mail (port 25) and another that was a web server 
(port 80), m0n0wall can map out across to different internal IP 
addresses with ease.  If you are using m0n0wall for DHCP, it might be 
helpful to reserve those internal IP address for those machines so that 
your mapping will always match up if you reboot the machines, etc.

Thanks,
