Windows 2003 VPN question/issues

I am dealing with a strange VPN issue.
The attached PDF shows my WAN/LAN config at the office.

The VPN Server is a Windows 2003 Standard With all updates applied.

I have about a 40-50% loss of all packets.
The server;
HP DL145 G2

RRAS is listening on
Internet connection sharing is turned off

There are no static routes set up on the LAN

Firewall has the following ports forwarded;
1723 -
500 -
50 -
51 -
137 -
138 -
139 -

plus a few that are special for a given item

Any sugestions?

Can you check for errors on the physical interfaces wired and wireless of the firewall and router?
Also what is ping looking like to somehting right off the firewall like a printer in the diagram? That would at least eliminate up to that point and give you less to debug.
And the 2 cables to the server, is it possible there is an issue there? Can you disconnect one at a time and see if you get better ping performance?
