      ?

      Nope, This is the rule I added:

      I agree, not strictly needed, but you've set up a DHCP server on OPT1 ?
      ( just add a pool like 192.168.3.2 -> 192.168.3.100 )

      I believe this is not necessary cause this interface has only the PC connected with static IP.

      Yeah, right, and not settings DNS can/will create "issues"

      DNS is setup as 192.168.10.5 where I have PiHole

      The main issue is that my PC, connected to that new interface, is not able to communicate with any other interfaces. Somewhere I read that I need to configure bridge between LAN and OPT1 (aka: PCDESKTOP). But in this way maybe I'm able to reach GREEN, but not BLU and RED.

        So no ICMP, No UDP (so no DNS) ...
        Are you sure ?

        DNS traffic won't reach this 192.168.10.5, you know why now.

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??

          Why? doesn't the "*" means allow all connections?

          But the main issue is not in DNS. The issue is that 192.168.3.7 can't communicate with the whole GREEN network 192.168.10.1/24

            This :

            21ca0b68-d480-47f3-8261-7f6ef36b9969-image.png
            means : only TCP (IPv4).
            This rule won't pass UDP, neither ICMP.

            This :

            b0cb4036-3fea-4f2e-86a9-fb3157f79bf5-image.png

            means everything (but not IPv6).

              Do you actually need that to be in a different subnet? You could just add the port to the LAN vswitch/bridge in whatever hypervisor you're running.

                DAMN! I missed the protocol config, thank you. I'll try it as soon as possible

                No, I don't need different subnet, I just follow the guide :) . But honestly same subnets it's even better.
                I'm using Proxmox but it will be complicated to bridge them, cause I have already bridged the GREEN ports for LACP:
                alt text

                Is there any other way to avoid different subnet in pfsense?

                  Oh that's easy then. Just add the NIC to the Linux Bridge you have configured for LAN in proxmox. Remove it from pfSense entirely.

                  Pretty much exactly like you tried to do in that screenshot but remove it from any other bridges first.

                    Do you mean something like this?
                    alt text

                    Currently 2 GREEN interfaces is bridged to bond0 in LACP, so do you mean add eth6 (the new interface) to that bridge?

                      Yes assuming eth6 is the new NIC you're adding there. vmbr7 will act as a swtich there for traffic between your desktop and the rest of the LAN. That means no loading on pfSense for that traffic.

                        @stephenw10 Thank you very much, it works perfect!!!
                        I don't know why I didn't think before at such simple solution 😊
