Hi.  I want to access a PC remotely, but I don't want to expose the PC
to  the Ethernet.  I have a WireGuard server (with the WireGuard IP:
[11.0.0.1](https://11.0.0.1/)) and the 2 configuration files, one for
each PC.

I  when I am connected to the WireGuard, I can ping the server, but it
doesn't connect to the SSH. I also tried to have the WireGuard config
for the server run on the PC that I want to access, but when I tried
to  connect via SSH, I get "Wrong password" even if I am putting the
correct  password.

So the question, I should do something different to get a SSH
connection?

You need to setup the wireguard ip in ssh config.

It looks dumb, but did you happen to have not specified the correct
username when you ssh?  Is your ssh command in this syntax:

    ssh username@host

or

    ssh -l username host

Outside of fixing your SSH issues, you should change from 11.0.0.1 as
that's a public IP. See RFC1918.

The ssh server will just see the incoming connection as existing on
the same network, or at least if you’re using masquerading (which I
assume most WireGuard users are).

If you can post your conf files for both pcs it would be a good start.

Did you use a third party service to set up WireGuard like pivpn or
tailscale? Can you normally ssh between pc’s while local? Did you
enable port forwarding for wireguard traffic on your router?
