pfSense - WireGuard optimal settings

[Teng Teng Toa 2]

Is there any tutorial for setting up AirVPN on pfSense with WireGuard protocol?
Any settings I need to set (MTU, MSS, etc?) for an optimal connection?

I have a 1gb/s fiber connection PPPoE for what it's worth...

Hello!

PPPoE adds some overhead https://en.wikipedia.org/wiki/Point-to-Point_Protocol_over_Ethernet#Protocol_overhead therefore WireGuard interface 1280 bytes MTU is recommended.

Kind regards

Ok, thanks for that!
Do I need to specify MSS as well in my pfSense interface?
