      I have an interface on pFsense OPT5 that I have added in the GUI and make sure to enable afterwards (in the checkbox). It is configured as DHCP. When I connect a cable from a Cisco VPN router with DHCP-service running, pfSense OPT5 doesn't receive any local IP from it.

      The port lights up both at the Cisco unit for that port and at the pFsense port (and turns off when I disconnect any of the sides - I pulled it out). So it is sure it is correct devices on both sides. I have a lot of IPMI-devices from this Cisco VPN that gets DHCP-IP and when I connect laptop to the same cable as I use (pull out) to the pfSense OPT5 interface, it correctly gets an IP (like I hoped pfSense OPT5 would also).

      What could cause the traffic to not flow? I have tried to manually set the OPT5 IP to an static IP in the DHCP-net just to see if I could ping the Cisco VPN (so same network). I have also set the firewall to allow all traffic to/from this interface.

      Another step I did, was to disable OPT5 interface from GUI and then I got no green light on either side (as one would expect and should see).

      I do see this in the statistics - note the interrupts:

        Most likely it's not the interface you think it is.

        Try running ifconfig -a and check to see if any of the available NICs show as linked.

        If that a new NIC you have added? What NIC type is it?
