      Does PFsense support dual dhcp type wans now? e.g. I want to connect 2 cable modems.

      thanks

      PS I tried PFsense a long time ago and I think I had to drop it because it didnt support dual dhcp.

        You can have a second WAN as a DHCP client.
        However what you cannot have is the same subnet and/or the same gateway on two WANs.

        (although if you have two different gateways in the same subnet it would work but i dont think this is your problem :) )

        We do what we must, because we can.

          Thank you, does pfsense allow you to route between the 2 subnets?

          thanks again

            Yes of course.
            But if the clients in one of the subnets have another IP than the pfSense as gateway you will have to create a static route on their gateway.
            (or enable RIP to exchange the routing information automatically, although i like static routes for this kind of setup better).

              GruensFroeschli is of course completely correct, I was running two cable modems in DHCP mode but I found I was using static routes more and more. Then when one of the IP's changed it would screw it up. Not only that when a modem rebooted but not all the way I would get a link up but it would have a 192.168.x.x address and this would confuse things further. The most effective 'fix' is to bung a dirt cheep access point between each modem and turn its firewall off then you can set static IP's and add as many static routes as you like  ;)

              Check out my setup <= May take a while to load under IE
