I was trying to manually set up my wireguard VPN on UHF and had two issues. Hopefully UHF implements these suggestions.
MTU-There is no way to adjust this. I had a ton of pausing and buffering. I installed WG Connect so I could drop the MTU down to 1280 so the video would stop fragmenting.
DNS-There is no way for entering it manually.
It would also be easier if it could import .conf files for the VPN.
