      On my EX435 switch I have a static route to 192.168.50.1 which "was" the ASUS router and is now the 7100. So I believe it is simply putting the 10.x traffic directly onto the 7100 which it knows nothing about. (note: I'm stretching my brain here...)

        The route on pfSense for the 10.10.x would not impair the functionality even if it was not needed. Neither the outbound NAT rules did. In this case, pfSense would never get a packet for 10.10.x.

        However, you should know if your switch does nat.
        If you default route on the switch is pointing to pfSense, packets should get directed to it.
        So you could run a packet capture on pfSense LAN while you try to access an internet resource from a VLAN to see, what's going on.

          The 7100 is seeing 10.x traffic.

          Here is the results of a LAN packet capture:
          18:28:16.793704 IP 10.10.8.12.29620 > 8.8.4.4.53: UDP, length 32
          18:28:17.952164 IP 10.10.10.11.49268 > 8.8.8.8.53: UDP, length 59
          18:28:17.952415 IP 10.10.10.11.64554 > 40.97.190.2.443: tcp 31
          18:28:17.952794 IP 10.10.10.11.52456 > 8.8.8.8.53: UDP, length 59
          18:28:17.952800 IP 10.10.10.11.63862 > 8.8.8.8.53: UDP, length 37
          18:28:17.952807 IP 10.10.10.11.58518 > 8.8.8.8.53: UDP, length 37
          18:28:20.972454 IP 10.10.10.11.64554 > 40.97.190.2.443: tcp 31

          And here is results from the firewall:
          Dec 6 18:27:17 LAN Default deny rule IPv4 (1000000103) 10.10.10.11 17.253.5.202 ICMP
          Dec 6 18:27:20 LAN Default deny rule IPv4 (1000000103) 10.10.8.11:47105 8.8.4.4:53 UDP

            I see. Obviously pfSense doesn’t pass the packets.
            You need a rule on LAN to allow it.
            By default pfSense automatically creates a rule only for the LAN subnet. But 10.10.x.x lies outside of this.

            Additionally you need the route and outbound NAT rule as mentioned above.

              I created a LAN gateway of 192.168.50.2 and setup a route for destination addresses of 10.10.x.x to that GW. Is this sufficient?

                Yes, but don’t state it in the LAN interface settings, only in System > Routing > Gateways.

                However, also this does only matter on inbound connections.

                  I did not change any settings in interfaces > LAN

                  I went to System > Routing > Gateway and created the following:
                  Interface: LAN
                  Gateway: 192.168.50.2

                  Then into System > Routing > Static Routes and created the following:
                  Destination Network: 10.0.0.0 /28
                  Gateway: (selected 192.168.50.2)

                  NAT > Outbound:
                  4ae756d0-029c-40fc-ab75-cc47c382d529-image.png

                  I'm still not getting connectivity.
                  When I look at the firewall log I see both LAN and WAN deny of 10.x clients

                    FYI: It's late here.. going to pause until morning.

                    Thanks!

                      Can you post a screenshot, please?

                        Want to circle back with you regarding the /28 designation that you referred to previously. As I understand it a /28 only has 15 addresses so a 10.0.0.0 would have a range of 10.0.0.0-10.0.0.15. Whereas a /8 would provide a range from 10.0.0.0-10.255.255.255 which would cover all 10.x addresses. Shouldn't I be applying a rule with a /8 to cover each of the VLans I have within 10.10.x.x & 10.20.x.x (10.10.8.x, 10.10.10.x, 10.10.14.x, 10.20.0.0)?

                          Here is a screen shot of the firewall syslog:

                            Yes, I was tired yesterday evening.
                            For your networks you need at least 10.0.0.0/11 (10.0.0.0 - 10.31.255.255).
                            Or even add a separate route for each subnet.

                            Also the blocks by the firewall results of the too small range.

                              OK, seems that I have full connectivity working now. :)

                              I created rules for both the WAN and LAN interfaces allowing the traffic for the 10.0.0.0/8 network. Initially I had a mistake in only allowing TCP, which showed up in the syslogs so changed that to ANY and now my clients are connecting.

                              After multiple days of chasing the configuration I'm quite happy that it's now working. THANKS MUCH!!

                              Now onto my next step of getting the NORDVPN working. (AFTER SAVING MY CONFIG!)

                              Cheers and have a great day!
