Please Help!! Remote Desktop using XP Pro and XP Home behind SBC 2Wire router and Linksys BEFVP41 VPN Router

I am trying to use the Remote Desktop feature to access my personal
office.

Situation:

Office has 2 computers 1. Windows XP Pro and 2. Windows XP Home. My
office has SBC DSL that is connected through a 2Wire Cable Modem then
plugged into the Linksys BEFVP41 VPN router that is mandatory for my
billing software.

I am trying to connect from home using my Windows XP Pro laptop also
on SBC DSL.

I tried to call Linksys and they had me open up their router port of
3389. I then figured out that the 2Wire Cable Modem had a firewall
and also needed to check the box in the configuration utility to "let
others connect to this computer".

I set my office XP Pro machine to allow users to connect to it and I
still am having trouble. I cannot connect to it at all.

I am not sure exactly which IP address to connect to using the XP
Remote Desktop application.

I have a number of IP addresses

63.xxx.xx.xx I think is the regular IP Address
172.16.xx.xx I think is the Cable Modem
128.68.1.1 I think is the Linksys VPN Router

I believe using the RD utility I would try to connect to the regular
IP address but then how does it know which machine I am trying to
connect to from there?

Can anyone offer any assistance?

ALSO and this may be totally separate but using the Linksys VPN router
can I make a Remote (possible VPN) connection to the XP Home Office
computer from my home/hotel/other location (laptop using XP Pro)or
does my office computer need to be XP Pro as well?

If in fact the DSL modem is also a firewall, which I understand some are, then you also need to
forward TCP Port 3389 through it to the WAN IP of the Linksys router. Then the Linksys router needs
to have TCP Port 3389 forwarded to the private static LAN IP of the XP Pro desktop your trying to
access/control. Call using the public IP of the modem. A bit convoluted but necessary...

XP Home can not be accessed with Remote Desktop. You could use UltraVNC. In that case you need to
repeat the above process and forward TCP Port 5900 through the DSL modem and the Linksys router to
the private static LAN IP of the XP Home box. If you use UltraVNC over the public internet also use
the encryption plug-in...

...OR upgrade the XP Home machine to XP Pro...

Alternatively, you can use WebEx Access Anywhere. It doesn't require
you to open up any ports beside port 80. So you don't have the
vulnerability of opening port 3389. It is have a promotion that you
can use it for free until 2005. Give it a try.

Good luck,
