MS Remote Assistance - TCP/UDP/Ports?

[tec92407]

I have CP NGX R60 on Nokia. I have two internal nets (LAN1 and LAN2) on separate interfaces of the firewall. I can establish a remote desktop session from LAN1 to LAN2 but cannot establish a Remote Assistance session.

Are there other ports I need to open? Can anyone help?

thanks

open your smart tracker and view what is being blocked
then open those ports

Check to see if there's anything in SmartDefense that might be blocking this. SmartDefense might consider this to be a hacking tool...

tec92407,

Remote Assistance uses random ports to connect, I have had no luck getting this working on our end, gave up and told them they could only use Remote Desktop.

Here is additional info:

Yes, Remote Assistance will work through any firewall when Port 3389 is opened. When using Windows Messenger, dynamic ports are used in the helper's ticket. The helper's computer uses the first available TCP port above 1024.When using the Windows Messenger method, the requestor makes the first attempt to establish a Remote Assistance session using the helper's IP address and port number in the ticket. Reference Q306298 Explanation of the Windows Messenger Reverse Connection Process and Q301529 Supported Connection Scenarios for Remote Assistance for more information.

Remote Assistance can also push through Windows XP Internet Connection Firewall (ICF) without enabling TCP Port numbers.
