Unassigned Interface

[Heiko910]

Hey guys,
I am new to OPNsense.
I have searched this Forum and read every post remotely similar but nothing lead me to the solution.
I have spend multiple hours on google as well to see if I can find the fix for the problem but no joy.

I have been successfully running OPNSense on a fan-less router from Ali-express with Wireguard for about three month now. So far no problems, I am running it on a piece of hardware that has 4 NICs and I am currently only using 2 of those (IGC0 and IGC3). One is the WAN the other the LAN.
I was trying to establish a LAN Bridge but when I try to add an interface in Assignments non of those unused NICs are available in the drop down.
In Interfaces/ Overview the two unused NICS are showing as "Unassigned Interface IGC1 and IGC2". Both are listed in the Overview with MAC address but they are both showing as "Administrative disabled".
Since the hardware I am using  has a HDMI out I went into the terminal and configured those port as OPT1 and OPT2 but once I went back into the WebUI OPT1 and OPT2 are not showing in Assignments.
I am running the latest version 22.7.10_2-amd64 I did restarts. But still no solution.
Any advice would be appreciated.

Hi everyone,
My post didn't get any replies but I managed to fix the problem myself.

I wasn't able to assign two of my ethernet NIC ports to a new interface in the Assignment section, not because anything was broken but because those to ports were already assigned elsewhere.
I looked in to the Other Type section and saw that there was a LAGG created, that used those two ports. Since I am not using a LAGG on this router I just deleted it. That freed up the port and now they are available for assignment.
I thought I put his here in case anyone ever has the same issue and maybe this reply will help.

Greetings,
Heiko

Hi, and welcome to OPNsense.

The "usual method" of multiple NIC on pfSense or OPNsense if you have 4 NICs is:
1x WAN - Your Internet Connection
1x LAN - You LAN port, usually if you need more ports, you connect this to a switch
2x OPT1, OPT2 - You can use this for VLAN, DMZ, LAN2 subnet, etc, and if you need more ports, you connect them to a switch.

However, the alternative which you are asking for is probably this:
1x WAN
3x LAN (Switch)

The guide is here...
