i am trying to use remote assistance help 3 people who
are behind a router. i know the public ip and each has
an assigned local ip. port 3389 points to 192.168.1.102,
port 3390 to .103 and 3391 to .104 (for use w/ remote
desktop). but i want the person sending the ra invitation
to watch what i am doing so they can learn.

so, does ra invitation only emanate from port 3389?
(which in this case is always forwarded to 192.168.1.102)
is port 3389 the only way into remote assistance?

sorry if this is confusing - i am all muddled up.

thanks for any help.

If the router is UPnP capable then it should be automatic...

http://support.microsoft.com/default.aspx?scid=kb;en-us;Q301529

With that said, however, you could use the file method of invitation and modify the RCTICKET field
in the file to reflect the different port for each Novice and the public IP.

http://support.microsoft.com/default.aspx?scid=kb;en-us;Q300692

In that case each user would issue an invitation to you which you save on your PC somewhere. You
modify each file for the correct port. You would also need to make sure the router is configured to
forward the correct port to the correct user at the remote end.

thanks sooner al-

a response so soon!

i have been using email invitations and modifying as
necessary.

from your link http://support.microsoft.com/default.aspx?
scid=kb;en-us;Q300692 i gleaned this nugget:
The UPnP NAT Server begins mapping traffic on the IP:p ORT
to port 3389 on the NAT Client Novice computer.

but on the router, 3389 points to only one computer
does the UPnP NAT server overide the router's forwarding?

a little more research on the web - one site said to use
port triggering w/ rcimlby.exe for the different ports.
does that make sense?

thanks so much for your help!

If the router is not UPnP compliant, then your only recourse may be to open multiple ports, ie. one
for each client, on the router, ie. User 1 - Port 3389, User 2 - Port 3390, etc...and change the
RCTICKET field in the invitation. Note you will need to change the listening port on each of the
users PCs also in order for this to work...

http://support.microsoft.com/default.aspx?scid=kb;en-us;Q306759

Reboot each PC after making the change...

As you can see, UPnP makes this so much more easier, if of course it works as advertised...:-)
