[FEATURE] - wireguard tunnel handshake only via data

[Peterkal2112]

Is your feature request related to a problem? Please describe.

On airport free public wifi or on train public wifi or any open public wifi, mosty are wireguard connection tunnel blocked (mosty via deep paket inspection where the firewall is dropping wireguard handshake packets)

Describe the solution you'd like
I have a gl.iNet travel router where i can make a workaround that i will connect to my lte 4G data from my phone and make the wireguard handshake via data and after that will connect to public wifi and the payload via tunnel is coming via wifi... The firewall is blocking only handshake, this kind of blocking can be circumvent via doing a handshake only via LTE mobile data 4G or 5G which is not consuming so much data...

Describe alternatives you've considered
Having travel router and connecting android phone via data but that is impractical, costly...
Or setup the wireguard server via SSL port or proxy which is server side setup, can be complicated to setup or cannot be done on some devices or providers...

Additional context
Need just one Simple switch button in WG tunnel under auto-tunneling where there will be "handshake via data"
