VPN - Can see server from home, but cannot see home from server

D

I have a server running Windows Server 2003 and a laptop running
Windows XP.
When the the laptop is in the office and connects wirelessly to the
server, everything works fine between the laptop and the server in
both directions.
When I take my laptop home and connect to the server via VPN however,
I can see the server and use all of its resources without any problem,
but the server cannot see my laptop.

For example, when I'm connected via VPN to the server from home and
type \\servername\sharename from my laptop, I can see everything I
should be seeing and am able to add and edit files on the server. But
when, using that same connection, I go to the server at the office and
type \\laptopname\sharename, I get an error message saying it cannot
find the laptop.

I have a DLink modem at home and I connect wirelessly to it. I have
another laptop running Windows Vista, and when I have that laptop here
at home connected to the VPN, that laptop can both see and be seen by
the server and it has bidirectional file editing working too - so it
is not some setting in my modem/router.

I have made sure the Workgroups match and that all firewalls and
antivirus programs are completely turned off. My guest account on the
laptop is enabled (if that makes any difference).

Also one quirky thing - when I'm connected via VPN from home, my
Internet and email don't work. I know I can uncheck the Default
Gateway box to make those work, but then the file sharing doesn't
work. I don't know if this is related.

Any help is greatly appreciated.

When I'm connected via VPN from my XP laptop at home to the Server
2003 desktop at work, I cannot ping my client from the server but I
can ping the server from my client.

When I'm using the same VPN connection (home to office) from my Vista
laptop, I can ping both ways.

I need the 2 way connection on the XP machine just as I have it on the
Vista machine.

My PPP Adapter IP on the XP laptop is 169.254.220.129
My PPP Adapter IP on the 2003 Server (RAS Server) is 169.254.212.35

Here is my server's routing table:

This is pretty far over my head, although I'm in the midst of a 6"
thick networking book trying to figure it all out! Any help would be
greatly appreciated.

Yes, the Vista machine works when connected through the same router.
Both the Vista and XP machines are connected wirelessly to my home
router.

I've tried enabling the firewall and allowing the server's IP through,
but no luck, so that was when I just disabled it completely. I've
also tried allowing the server's IP in the router on port 1723, but
I'm not sure I'm doing it correctly, or even if that is the problem.
