      Also check System -> Advanced -> Firewall/NAT tab
      Bypass firewall rules for traffic on the same interface should be checked.

      Why?  The downstream router should be routing between those subnets.

      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        Keep in mind that an "old cisco router" is not a stateful firewall and will happily pass asymmetric/triangle routed packets.

          In the event PCs on LAN segment are using pfSense as default GW, traffic might not need to be inspected going back out LAN interface to hit the router.

          Good point!
          Which is why I asked: Is the pfSense LAN IP the same as what you had on the old Cisco router?

          Bottom line, the original post is kinda thin on details, so we're just guessing at this point.

            The new router LAN ip is 10.33.217.253 the old one is 10.33.217.2. I dont have access to  the vendors router. I called them to verify that they didnt have to change any config in there router.

            Attached is  the lan rules.

            Why not duplicate what you had that was working - One route for 10.32.0.0/16 to 10.33.217.1 ??

            I tried that as well set route to 10.32.0.0/16 to use gateway 10.33.217.1

                @awebster:

                It looks like you've configured the routes properly, but please also share LAN config and Firewall rules.
                Is the pfSense LAN IP the same as what you had on the old Cisco router?

                Also check System -> Advanced -> Firewall/NAT tab
                Bypass firewall rules for traffic on the same interface should be checked.

                Should I check in System -> Advanced -> Firewall/NAT tab
                Bypass firewall rules for traffic on the same interface should be checked.

                what does this actually do??

                  Check the routing on the LEADS router.

                  If you change the IP of your router, LEADS router has no way of getting the traffic back to your Internal networks.
                  Your internal network's machines should have pfSense as default gateway OR route for 10.32.0.0/16 to LAN IP of pfSense.
                  LEADS router must have routes back to your Internal Network's IP range(s) or default route back to 10.33.217.2.

                    I had them verify there settings and they said everything was ok. I will call them tommorrow again and maybe I will get to talk to somebody else. I know it has to be something on there end but what about the

                    lso check System -> Advanced -> Firewall/NAT tab
                    Bypass firewall rules for traffic on the same interface should be checked.

                      When checked, pfSense will not apply firewall rules to traffic entering and leaving on the same logical interface.

                        I checked the box and it seems to be working now. I also verified with the vendor of there settings and he added routes for the  pcs that only use the software and so far so good.
