Multiple External IP NAT

ryan247

Hi thank you all in advance for reviewing and possibly advising.

I have a my pf setup with external IP and I can reach it and any NAT I do with the external facing IP is fine however I also have 5 other usable addresses for devices that we have ports already used and unable to use modified ones.
I am unable to access using any of the other ip's example below

External94.x.x.83 for fw and I can access - any server behind with nat so 443 - 192.168.1.1 works fine, 22 on 192.168.1.2 etc etc
Additional External 94.x.x.84 with server 192.168.1.3 port 22 no access
Additional External 94.x.x.85 with server 192.168.1.4 port 80 no access

I have the firewall WAN ip with a /20 same subnet as i have for the address range and also added the GW they all use so no issues I can see there. I cannot see anything in firewall logs

Seems, you have a subnet, that you want to use on WAN. So you have to assign each IP you want to use to the interface.

Firewall > Virtual IPs
Select WAN and type "IP alias" and state your IPs with the proper subnet mask one by one.
