RDP behind firewalls over the internet

Hello
I am trying to remotely administer my friends pc at school from my pc at home. At home I have a Netgear DG-814 Router, at school my friend is the school firewall. If theres any ports that have to be allowed in to my pc, thats not a problem, I can just forward tehm in my routers config, but my friend is just in his dorm and he has no control over any of the ports being allowed in to his pc. Maybe theres a way to do it through port 21? Its most likely open.
Ive searched and I heard that VPN might work and Ive tried to get it going but with no luck.
Im tempted to go fot that GoToMyPC thing thats advertised everywhere, even though its quite expensive.
thanks!
 
If you are just try to control his PC, use some thing like Ultr@VNC and set it to use port 21. It has a Java viewer so you don't need to install anything on the client computer.

Yes, you just have to tell it to on the host computer. Then you enter xxx.xxx.xxx.xxx:21 where the Xs are the ip of the computer and ":21" tells your browser to use port 21.

Ahh! But my friend is behind a firewall! I dont know his IP. I only know the ip which is xxx.xxx.edu (school network)
Actually i do know his ip, its internal though (192.168.0.xxx), i dont know if knowing it is of any use (telling vnc to route itself to that ip???? i dont know if its even possible)

I'm not sure if I am misreading this or not - but if you friend is behind a firewall/router > NAT device then a port is going to have to get fwd'd from that device to his internal 192.x.x.x address...

yes but htats the thing no ports can be routed on the host side. Only on the client side. Anybody have an idea as to how to get around this?
 
i do this at a workplace i manage,

all the pcs and servers have 192, addresses but the router has the conection

i installed www.dynu.com the basic client that allows me to see the pc i need, all ya need then is to find a open port to connect to.

skip RDP and use vnc. vnc can reverse connect, ie the server can initiate a connection to the client, that way you can pass through the proxy/nat from the inside.

Great!!
Ill try it. Does the server have to try and connect using any specific port?
The viewer will have to listen on a specific port, which im gonna have to forward to myself, right?
thanks
 
k it worked!!!
Only one question
When my friend starts up the server, it doesnt show up in the taskbar. It sometimes shows up in the task manager as winvnc.exe, but no icon in the tray. When for some weird reason winvnc.exe shows running in the task manager, id tell my friend to run "C:\Program Files\UltraVNC\winvnc.exe" -connect then type in my ip.
If i tell my friend to start the vnc server, simply nothing happens no icon in the tray and no winvnc.exe in the task manager, weird.
Does anybody know why this weird thing happens?
btw i had to forward port 5500 to my ip, i figured that id have to though
