Due to change of branch location make my friend need to remote his computer (windows xp) office for efficiency, we discussing about using remote desktop in reality.

Remote desktop use port 3389 so the schema to remote is :

outside –> port 500 –> firewall forward –> 3389

Since load balancing policy, specific address need to remote desktop, e.g :


then firewall will forward that request to port 3389

what if no firewall involve then direct public address accessible :

In general :

Windows XP Remote Desktop PORT : 3389

80? no it’s web server

21? no, it’s ftp

25? no, it’s email

no more question please 😉
