VPN over dedi box (ssh connection lost)

Recommended Posts

Hey there I recently got myself a dedi box for torrenting and stuff and I would like to redirect all traffic through a VPN.

 

I managed to get eddie installed on Ubuntu 18.10 but whenever I try to connect to a server it just lags and eventually disconnects. 

Enabling network lock also kills my SSH connection/VNC connection and I can't ssh into it until I reboot.

 

 

What I need: 

Being able to SSH into the box from my laptop and desktop while the box is connected to a VPN. Also when its not connected to the VPN.

 

I've searched through the forums and read something about configuring "routes" in the settings but it didn't work.

 

How can I set this mess up? Any help would be appreciated!

 

Thnx in advance.

...

For completeness, the comments below may help demonstrate what the issue is.

 

As quick and dirty way to sustain the SSH connection, add a routing table entry to direct traffic to your SSH client over the original gateway. Something like this:

sudo route add -host 111.222.333.444 gw 555.666.777.1
 

There, "111.222.333.444" would be the address you connected from (as shown when you do "echo $SSH_CLIENT"), and "555.666.777.1" is the original default gateway (the entry with a "Genmask" of "0.0.0.0" when you do "/sbin/route -n").

 

SSH connections from anywhere else will still fail.

...

 

You need that route set up before you start the VPN. There are more complete solutions there too.
