Hello,

I have a a watchguard fireguard XTM 300 series and I need the to achieve following:

I have 5 public IP addresses which I need to allocate for one of my applications.
Each external public IP traffic needs to be directed to the private network to the relevant private IP address as illustrated in my diagram.

Is this possible?

If so, could someone please give some instructions on how to do it ?

Many thanks in adavance

I'm not familiar specifically with the 300 series Fireboxes, but I believe that they use the same Fireware XTM operating system as other Watchguard firewalls.  Given that, the way to do this would be to set up a 1-to-1 NAT entry for each of the external IPs, NATting them to the corresponding internal IP address as you've indicated on your diagram. This would redirect all incoming traffic on each external IP to the internal IP specified.  Other than that, you'd just have to add any firewall policies you need to allow the incoming traffic as you normally would.  The firewall will automatically use the 1-to-1 NAT entries to redirect the traffic for any policies that you set up.
