Our company has multiple Windows servers running behind a NAT firewall. We would like to provide Remote Desktop access to these machines to our users.
One of the solutions is by port forwarding. We can set up RDP to run on a specific port and forward that port at the from the firewall. However, this opens up a lot of ports at the firewall and we don't want to use this strategy.
I was thinking if there is a solution similar to ssh gateways. (Is there a name based virtual host SSH reverse proxy?)
Is there any other solution.
