      There are too many complications in trying to put two WANs on a single NIC, it's really ugly. Just add a NIC and keep only one WAN per NIC.

        You could of course use two VLAN interfaces on the same physical NIC, but that implies a managed switch et al.

          We have a pfsense appliance and seem to be having the same issue, our second WAN has got an IP from the ISP but it won't show as online, can't ping google DNS. We know the internet for that wan is working if we patch a dhcp laptop into it, the internet works.

          We are using the C2758, we have one wan plugged into the top left port, and the second wan plugged into the bottom left port. Are you saying we have to install a second NIC to this appliance in order to use two WAN's? Because we have two wans working on another gateway but it's the SG-2440 appliance. Why is it different?

              Absolutely not what I'm saying.
              You already have four (4) NICs in your appliance.

                Sorry I've read that page it doesn't help. We have it all configured correctly as far as we can tell. I'm not an expert but the guy I work sure is but he is stumped too. It just doesn't make sense. The gateway is set to dynamic because the ISP gives out an IP, it's a UNDI port on a NBN (National broadband network) NTD. You can patch anything in there an if you are set to DHCP you will get on the internet.

                If it's so obvious to you what I'm doing wrong can you please just tell me? Give me a hint or something?  :'(

                I just noticed this, we are monitoring google DNS to say if the gateway is up or down, but in here it says the ISP is also using google DNS, could this be causing an issue? It's weird because the gateway appears to be up but we can't ping or traceroute etc…

                  But it's not like each of those 4 Ethernet ports are seperate network interface cards..? They are a quad port nic.. right?

                    This is what you are doing wrong:

                    I am having one LAN and one WAN interface with two gateways.

                    ::) ::) ::)

                    Now, go read the docs a couple more times and please tell us where do they suggest to create a single WAN with two GWs.

                    ::) ::) ::)

                      Really?

                      @andyroo54:

                      …our second WAN has got an IP from the ISP ...

                      It's the typical scenario: "I have the exact same problem! Well, totally different setup, but EXACTLY the same problem. Promised!"

                      Andyroo54, please start a new thread and post screenshots of your interfaces and gateway configs in there.

                        Still separate interfaces like em0, em1, etc… for the OS.
                        A quad-port NIC is NOT a switch. Those are 4 dedicated NICs on a single plug-in card.
