Connect FROM LAN to VPNed machine

Using RRAS, machines are connecting to my LAN, though a different
subnet.
>From my desk, I cannot ping their machine via IP, or reach any ports
EXCEPT I can RDC to their machine.

I am assuming that there is something in RRAS preventing this, but I
cannot find out how to modify that setting. For example, I have an
application that allows me to remotely manage the user's laptops, even
when VPNed, on TCP port 9999.
How would I tell the RRAS server to allow access from its LAN port to
the VPNed machine's port 9999?

Thank you in advance!

Assuming this is a PPTP VPN, if you can RDP, you should be able to ping
the VPN client. IF these are XP clients, the firewall must be configured
to allow ICMP echo requests/replies or disabled. I have a PPTP VPN
client connected to my LAN and I can ping the IP Address of the VPN
ADAPTER - you will not be able to connect using the IP address of it's
LAN interface (if you could, you wouldn't need the VPN).
