I am working on a Debian system at a sister company, and have a VPN set up between the 2 sites. I am able to Remote Desktop onto any of their other servers, but no their Debian server. I am able to access the IP address for the Bebian system through a browser on any of their network boxes, but cannot access from outside.
The only way I'm able to access the Debian box is to RDP onto any other server within their system, and then RDP from there to the Debain system. Doing this way though prevents me from sending files as I am unale to SSh or PFTP to the Debian box form my VMWAre testing system's Command Terminal, which I have been using throughout previously.
In the past I found a command that was entered into the Debian terminal through RDP that opened up a port on the box, that since then enabled access, but following a recent server reboot, the connection has once again been lost.
Is there a command that will sort this problem, when entered into the Command Terminal of the debian box whilst RDP'd onto it?
