setting up remote network with adsl router and remote PPTP access help

[Ollie]

Hi,



I'm planning the installation of a temporary remote network for some of our
users who need to connect to head office via PPTP / VPN. We are going to put
in an ADSL router for there internet access, and have been testing this
outside of the network.



The problem we have come across is that while we can connect any xp computer
from the same LAN to VPN, then disconnect , we only seem able to have one
connection at a time and the other computers error with 721 the remote
computer did not respond. After we disconnect and leave for a while we are
able to establish another one connection, and the others error again. What
could be stopping us having more than one connection at a time from the same
LAN???



The basic setup is, (remote office)XPclients x3 --->
ADSL--->INTERNET--->(head office)INTERNET ROUTER---NETSCREEN 25
FIREWALL---PPTP----TERMINAL SERVER



Any help will be much appreciated
