can't get rdp working but terminal services is working on ..

Archived from groups: microsoft.public.windowsxp.work_remotely (More info?)

i have setup vpn using cisco pix and windows terminal server on W2k servers
this works perfectly from home.
i dialup to the vpn get connected and can then connect to any of my 3
terminal servers.
i now want to connect to my office pc which is xp pro sp2 but can never
connect
or get to logon screen. i have xp firewall on my machine with port open for
remote
desktop (but have turned off also in my attempts)
i can connect in my office to my machine from any other so my machine is ok.
the vpn seems ok as i can connect to the servers.
i set my machine up with a fixed ip but still no joy

i can't ping my machine from home but i can ping the servers. maybe a clue!!!
i have used the port query tool from microsoft
my servers are not filtered for port 3389 but my machine seems to be when

me thinks this is the problem but i don't understand how i can connect to
the servers and not my machine

anyone any ideas
