One WAN Interface Multiple IP Subnets



  • How do you configure multiple IP subnets into one WAN interfaces

    I have a IPv4 /29 and a IPv4 /27 subnets I want to configure on one interface (they both have separate gateway) there is no documentation at all explaining how to do that (in windows it's so easy you just add another IP, anyway)

    pfSense gets assigned one address on its WAN port.  From there you assign VirtualIPs using the additional IP addresses your ISP gave you.  Set them up as IP Aliases and they should be on a /32 subnet.

    Oh, wait, you have two different gateways.  Not sure this is going to work.  I added another physical NIC to achieve this, plus I wanted physical separation of the WANs.
