VPN problem with Windows XP

[Guest]

I have a VPN connection problem.
In a branch office, I have a Windows 2003 server as a part of a workgroup
network, and it is the DHCP server. In addition, I setup a Windows XP as FTP
server and gateway server.
These two computers have two NICs, and one of them has external IP address
and the other one has an internal IP address.
Because I have a problem uploading files larger than 10MB through the
Windows 2003 server, I setup the FTP server as the gateway of the internal
network.
However, after I changed the gateway, there is another problem with VPN (not
FTP).
Since this office is a branch and there is a VPN server in the head office
with a DC, all users has VPN connection to the server in the head office.
After they connected to the main office through VPN, they cannot ping the
DC, and from the DC cannot ping the VPN clients.
In addition, UNC (Universal Naming Convention) doesn’t work as well.

We have two issue here. make sure no firewall blocks the ping. To use UNC over VPN, it is better to have a WINS server. the follwoing links may help,
