Remote Assistance only one way

[bjr]

I have a Vista machine (with Vista Premium loaded) connected via
Ethernet to a D-Link Dir 655 router with MAC Filtering enabled.No ports
are forwarded on the router.
I can send an RA ticket to a friend with with a Vista machine( wireless
to the router) sitting behind a DSL/modem wireless router and he can
control my machine with no problem.

However, when he sends me n RA ticket, I try to log in via the password
we set up and I get 'cannot connect to the machine' message.

Any suggestions?

Do a simple test. Can you telnet port 3389?
