Slow Performance with Road Warrior Setup on OpnSense

[theprez1980]

Hey all -

For some reason my Wireguard connection is not performing well at all.

I'm running OpnSense 24.7.7 on a dedicated computer (specs: i7-7700 @ 3.40 Ghz CPU, 16GB RAM and an X550 NIC)

The local internet where the OpnSense computer is located has a fiber connection with 2000x2000 and routinely gets that or slightly above (ISP over provisions a bit) - I do not use PPPoE, I have a static IP block.  I've confirmed the physical link rate and all is well there. 

Offsite, using either an android or iOS device on a mobile network or another fast Wi-Fi connection with Wireguard connected I get around 80Megs down max. If I disconnect Wireguard, back up to normal speeds for the given connection.

What's going on here?   I followed the steps here:

Thanks
