Dear all,

Is there a way to SSH to a machine running openvpn? (I can get the real IP, of course.)

I can see my router passing packages to the computer in my network, but it never connects.

Any ideas?

Thanks,

Luis

If you're running a VPN solution, you have access to the local LAN - and can ssh to the machine's local IP (or DNS address). Access restrictions of your LAN apply, unless you configured your VPN solution specifically to put road warriors into a walled subnet - but this depends on your local configuration.

Thanks for the reply, slh.

But can I access the machine from outside the LAN? As I said, the connection request (from outside the LAN) reaches the router, the router passes the packet to the correct machine, but the connection doesn't get established. I see no message in the computer's logs about the attempted connection (using "LogLevel DEBUG3" in sshd_config). If stop the VPN tunneling, I can ssh without problems.

Running a VPN client changes the routing, in order to (typically) re-route everything through the VPN tunnel, you typically can reconfigure it to whitelist a local subnet.
