Single NIC pfSense

Would like to see a video with single NIC pfSense going into a managed router on port 1 (LAN) and WAN (port 2). Would like to see if that will cause any bottlenecks ???

The speed would be limited due to WAN/LAN being shared on the same interface and I can’t think of any good reason to spend the time making a video on that topic.

I made this video already,
