Hi Alexander!

This is no problem.
You can use either "1:1 NAT" to map WAN IP's directly to LAN hosts - or
you can use "Server NAT" combined with "Inbound NAT" for more advanced
mappings like:

WAN IP 1/Port 80 -> LAN IP 1/Port 80
WAN IP 1/Port 21 -> LAN IP 2/Port 21
WAN IP 2/Port 25 -> LAN IP 2/Port 25

...and so on. You probably get the point ;o)

We wouldn't want it to listen on all IPs on a subnet (I think this is
what you
mean - appologies if I am wrong).

We are assigned 12 IPs from our ISP and need to make use of several of
these for
different purposes.

For example, if we want 2 webservers behind the firewall we would need
forward port 80 on one IP independently of port 80 on another IP.

Another example might be using an IP for a permanent VPN connection and
for our roaming VPN clients.

The second example might be fine over one IP but the first example

Thanks for any help.
