I'm running ubuntu 18.04.
I have a server that I SSH to, but I first need to turn on a VPN for that to work.
I want to enable other users to SSH to a port on my machine, in order for them to reach that VPN. So they ssh to port 12345(example) on my machine, and they are then on the remote machine.
So, a jumping point, I think.
So far, all attempts at using the -R
option have failed.
How would I do this? What am I missing?
Consider the following:
- My machine (A)
- The server behind the VPN (B)
- The machine of the person trying to use mine as a jumping point (C).
Both of the following commands have failed:
- On A
ssh -A -R 19999:localhost:22 B
- On B
ssh -R 19999:localhost:22
Edit: The VPN is a standard L2TP one that Windows allows you to set up.
