      hello, i have 2 isp

      cable modem (surfboard 5101) working in bridged mode, dhcp
      dsl modem (???) working in bridged mode, dhcp

      i cannot change the operating modes of these modems, since there is no access to do it.

      im not interested in load balacing/failover, what i need is policy routing (some protocols should go through the cable link and others through the dsl link)

      ive read the multiwan 1.2 document, but my understanding is that it only supports dhcp for router mode, bridge mode should have static ip (which i dont have).

      is this configuration possible at all ?

      or will i need to put a router between each modem and the pfsense box to simulate a router mode ?

        Set WAN as PPPoE and use your dsl line on that.
        setup an OPT, set it as DHCP and use your cable modem on that.

        then follow the multiwan document.

        We do what we must, because we can.

          thanks a lot !!! that was very fast !

          one question .. i'm not sure the dsl line is using pppoe, i've always managed it through dhcp.

          would it be a problem if i set WAN as dhcp ?

          this is also because i'm considering switching from dsl to cable, so i would essentially have two dhcp cable modems.

          and finally, if eventually i need load balancing .. would this setup work ?

            hi, any thoughts on this ?

            i'd like to make sure 2 bridged dhcp lines would work with pfsense, before going forward.

            thanks in advance.

              Yes it should, but so many different ways ISP can provide there service…..
              Don't know how separated the 2 cable lines will be, but it could make more sense to have a phone and a cable line.

                  Hello, I finally got the hardware needed for my solution. It's working, although not perfectly.

                  Below is a crude diagram of my connections

                  The problem I'm having is this …

                  I've set up a firewall rule to route LAN traffic to port 119 on OPT1. It works, traffic destined for port 119 is routed through OPT1 but every now and then, traffic completely stops. And it resumes, and it stops, and so on.

                  Anyboyd has any idea why this could be happening ? If I connect the OPT1 provider directly to the pc, it goes full speed without hiccups.

                  Additionally, I'd like the rule to filter based on the ip/port combination (192.168.2.5/119). Right now im only filtering by port, since I dont think pfsense can see the 192.168.2.x subnet.

                  Any help is greatly appreciated, thanks in advance.

                    i've been reading some more and found a post which may help explain the problems i'm having (OPT cant run on DHCP).

                    so my action plan is to put a router in front of the OPT interface so it gets a static class c ip address.

                    as for the other problem, im thinking of converting the linksys switch into bridge mode, so the internal pcs should get their address assigned from the pfsense box.

                    any thoughs/comments ?

                      well, it took me a while but i finally figured it out.

                      the problem lies with the nic (dlink dfe-520tx). i put my OPT1 interface on the intel 10/100 Pro nic and it worked flawlessly, while the WAN on the DFE-520TX failed.

                      i have yet to replace the dlink nic (in the process of getting another intel 10/100), but i dont foresee any problems.

                      as for the the dhcp issue, i disabled the wan on the wrt54gl router and connected the pfsense LAN interface to one of the wrt ports, making it behave as a bridge. now all my pcs get their ip from the pfsense box.

                      i still have some work to do: port forwarding, openvpn, i want to be able to address the machines by hostname instead of ip, etc.

                      i'm attaching a network diagram for future reference.
