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.

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) 74.77.0.3 *(gateway) none – ldrrp May 14 '15 at 18:06
