Need help with VPN problem not allowing more than one connection

Hello.

We have an SBS2000, SP4 server with a Netgear FS116 switch, Zyxel Zywall 10
firewall, two nics, Speakeasy DSL internet with Static IP coming in through
DSL Modem.

An ipconfig /all is at the end of this post.

A few months ago we went from a one nic to the two nic system and we started
using ISA2000 Standard and paid Microsoft to get the ISA up and running.

The VPN for users to log into the server worked fine previously. More than
one user could VPN in at one time. Since we started the two nic ISA system
we discovered that only one VPN could be established at a time.

I thought maybe somebody in this forum could help us figure out why we are
restricted to one VPN at a time. Otherwise we will have to pay Microsft
again.

Any help would be gratefully appreciated.

Thanks,
Tony
