Is this port necessary for RDP to function over a VPN?
I have two NSA2650s at different geographical locations connected through a VPN. When I RDP from one client to another through the VPN, I see the normal port for RDP, 3389, but it's paired with another port, 55669. Where is this second port being generated from? I've been tasked with closing\blocking all non-critical business ports. Is this port generated dynamically at one of the firewalls?
