Multiple WAN subnets on single interface



  • Hello everyone, this is my first post. I am planning a new network and I am a bit lost. I will get 1 static public ip and 3 different public subnets. Each subnet has its own gateway and ip. I want to add all subnets on same interface. In past I configured pfsense with 1 wan subnet and virtual ips but now I don't know how will this go because each subnets needs it's own interface to configure subnets ip and gw. I hope you will understand what I need. There is no sub forum for my native language. Thank you!


  • LAYER 8 Netgate

    Put them on different interfaces or different VLANs on the same interface.

    Multiple subnets on one network segment is bad design.

    Have your ISP route the subnets to the single, static IP address.



  • Thank you for your reply. I already sent email to isp if they can route all subnets to one static ip. I hope they can because I have only 1 wan interface. If they can't route all to 1 ip, I will try with vlans. Is this ok or should I create vlans on wan interface in both cases?



  • I just spoke with my isp and they will route all subnets through one ip so everythig is fine. Thank you!
