Configure the second LAN interface.

[ohara]

I have OPNsense installed on a configurable router with 4 ports.

I configured OPNsense as follows:
LAN - igb1 - 192.168.10.1 - desktop computer.
WAN - igb0 10.200.250.25 -> Internet.

I would like to run another LAN interface - igb3 and quietly connect it to the TP-LINK router with WiFi.
How to configure igb3 to access router to configure WiFi.
Should igb3 connect to TP-LINK router's WAN port or LAN port?

The second thing is how to protect yourself so that OPNsense is not hacked via WiFi.

Hi,
I just spend the weekend trying this and found one video by Jason.
You can follow the video and use other lan ports for connecting to the access point.
