Hello
I have been struggling a couple of days setting up the connection from my Netgate router to my Wireguard Server. Some websites were not loading.
At the end it was fixed just adding to LAN interface (or the one/s that would go through WG) the MSS value to 1380.
I think this info should be added to the documentation.
I have found it here https://www.comparitech.com/blog/vpn-privacy/pfsense-wireguard-setup/
under Setting the LAN MSS clamping
Thank you

You shouldn't need to set that on the LAN.
The recipe already covers this by setting an appropriate MTU on the WireGuard interface itself (which was only recently added to the recipe):
https://docs.netgate.com/pfsense/en/latest/recipes/wireguard-client.html#assign-interface
It's possible you need to set the MTU for the WG interface lower than the recipe suggests, the numbers in the recipe are just common default guidance.
If you still have issues, post on the forum to follow up.
