Homemade WireGuard VPN on a VPS server

[rungeard]

@croulibri

So I need to create a new Wireguard client config for my Home Yunohost (the same when I create client config for my mobile phone or my computer) and then to tune my current Wireguard configuration on my VPS Yunohost with these two file, PostUp and Postdown, to guarantee correct port forwarding.

Yes

@croulibri

And then on my Home Yunohost, I need to install Wireguard as a client and to configure the client with information from the VPN Yunohost (local IP, server keys,…) and also to ensure correct port forwarding through VPN with two other files PostUp and Postdown.

Correct. You can try to use WiregGuard client App from @tituspijean for that (see [WireGuard Client] Call for testers). But you will need some PostUp and PostDown script in any case.

But I understand I should also set properly the reverse DNS, and this I have no idea how to do it. Is this to be done on IONOS administration webpage, or a server config?

It should be setup on the IONOS administration webpage indeed.

And finally, I understand I need to make additional tweaks for Matrix coturn to properly function, isn’t it ?
For Nextcloud, Dokuwiki or FreshRSS, no need additional tweak, am I correct?

Exactly !
