I have hardware router which allows to configure VPN. I managed to set it up on my laptop (debian Stretch) in the NetworkManager applet. So now I can connect from office to outside word using my home router as a proxy (when I check my IP it shows the IP of my router).
I can also connect to one linux desktop machine (debian Jessie), however not by VPN, but this is not an issue. The issue is that when I connect to my desktop I would like to ssh back to my laptop using VPN channel, so I could open the result in the local X server. The problem is that I cannot even ssh to my laptop when I try to use laptop VPN IP. What would I have to check/try in order to resolve the issue? Kind regards, Piotr
