I have a pfsense with a single wan ip, i want to assign multiple wan ip's. The pfsense machine is located on a vm machine with the other servers i wish to NAT forward. I want to give each server a wan ip address. The servers are all connected to the firewall with a internal virtual network interface. Can someone can help me on how to configure pfsense to NAT correctly.


enter image description here


Add the additional IPs as IP Alias Virtual IPs. Then configure 1:1 NAT to ensure that traffic to/from each of your servers is mapped properly.

  • Just to make sure, Interface = WAN for ip aliases and also NAT interface? If so, that doesnt seem to be letting traffic flow – ldrrp May 14 '15 at 17:44
  • Yes, the VIPs should be on your WAN interface. Then you'll need to create 1:1 NAT rules and the requisite firewall rules as well to allow traffic to flow. – EEAA May 14 '15 at 17:45
  • Still unable to get it working i.imgur.com/3bgzFic.png So i created the VIP, then added the 1:1 for WAN and then created the firewall rule: IPv4 TCP *(source) *(port) *(gateway) none – ldrrp May 14 '15 at 18:06
