I got Airvpn wireguard working on OPNsense using this link.
It works fine except I can't access the sites in the title. They time out. I imagine there are others but these are the only three I have found so far after approximately one week of usage.
I have tried different servers and for duckduckgo I tried the ip address but no results.
I am currently using the northamerican server. I have tried canada and a particular Toronto server with the same result.
Any help or suggestions would be much appreciated.
Thanks.

SOLVED: I got this working using a detailed rule for MSS clamping by setting the it to 1300.
Firewall --> Settings --> Normalization --> Disable Interface Scrub --> Create Detailed Settings Rule --> Set max mss to 1300.
