Remote assistance and NAT

Is it possible to use the remote assistance feature in Windows XP if I
(the helper) am behind a NAT router and the person who needs assistance
is connected straight to Internet.

And what about if both are behind NAT-router? What port(s) should be
opened?

Forward port 3389 to the local IP, or have them send you a email invite, which you can hack.

I copied the technique from an MVP named Patty H, quite a while back.

When you get the email requesting assistance,save the attachment to disk. Right-click, Open With, and choose Notepad. You will see a
line like this: RCTICKET="65538,1,192.168.0.4:3389;novicecomputer:3389, This is the private IP address and the name of the person
requesting help's computer, followed by the port number. Insert the IP address of the NAT router and port number in front of the
private IP address. (see http://www.whatismyip.com ) like this: 206.192.44.102:3389; And final line like this:
RCTICKET="65538,1,206.192.44.102:3389;192.168.0.4:3389;novicecomputer:3389, Save file.
