a vps isn't required, you can self host.

[@BACKSPIN9ball]

very unorganized I should say, you mdae this complicated than it needed to be

[@TomásLacunza]

Best and easy 2FA to config?

[@orion36270]

Thank you so much for this tutorial!

[@loveenjain]

I am running UFW on my ubuntu server, the IP tables commands which you created are for allowing the traffic or there is more to it?

[@loveenjain]

Mate this is the BEST wireguard setup tutorial video I have seen on internet... Excellent!!!

[@gmc9753]

If you're logged in as root, no need to use sudo.

[@Apollo-gs4dv]

Followed the instructions until this command: 'sudo systemctl start wg-quick@wg0'. The output is: 'client_loop: send disconnect: Connection reset'. After that I can no longer log in to my server

[@combatjeyj6234]

oh no you destroyed your net configs and restarted the service only way to fix it is to reset your install or if in a vps ask for support

[@gianfidimo1089]

Is it possible to install wireguard on a server that uses a SIM for the internet connection?
Thank you very much for your reply

[@HetviShah-i6t]

how do you keep switching between client and server?

[@danielgumprecht]
