Kind of complex question regarding routing multiple public ips to multiple lans



  • Ok I have a pfsense setup as such:

    Connected to 1 cable WAN interface with a pool of 5 static IPs. I have 2 seperate lans on my network (Lan A: 192.168.1.0/24, Lan B VLAN6: 192.168.2.0/24)

    Currently both LAN's go out the same public IP.

    How can I get the 2nd LAN to go out the 2nd public IP address? I have another available nic port on both the cable modem and the pfsense unit if that leaves one option open.

    Thanks.

    Well you create a VIP on your wan interface of pfsense for one of your other pubic IPs you have.  Then create an outbound nat rule that says all clients on Lan B use the VIP as their nat vs the actual wan interface IP.

    Awesome. Thanks :) Got it to work. Had to set the rule generation to manual, and modify a couple rules that were in there for some unknown reason. I think it had to do with an old public IP we use to have.

    well yeah your automatic rules would of been natting that source network for you.  You might have been able to just use hybrid since I believe the hybrid rules are evaluated first.
