I am trying to set up Remote Desktop (RDP) access to my network. Currently, I can remote into my network using the standard RDP listening port. I want to configure the system to allow two users access using ports 3395 and 3396. I have done this many time with other networks and I think my issue is related to Windows Server 2003. The other networks had no server.
What do I need to do ON THE SERVER to allow RDP access with other ports. I know that I need to change the listening port on each machine to match the user I am trying to allow.
I have Windows Server SBS 2003 and Windows 10 clients. I have a Cisco ASA 5505 Firewall and an ATT 4111N modem. I have configured both for port forwarding and NAT rules. Thank you for any help provided.
