Wonder if someone has a good suggestion for udp port that's not commonly blocked on public wifi at airports and the like. DNS is out, so is NTP. Maybe Ike (500)? Something else ? This might be futile of course ...
@monk I already have a wireguard server listening on 53. These days many networks block 53 for malware/security reasons
@monk ah, I see. I suppose as a fallback option when other connection attempts fail it's a good backup .
