Concurrent VPN over RRAS-NAT problem

[Viet]

Our company has a VPN server in US. We are a branch. We
had a Windows 2000 stand alone Server on our LAN with 2
NICs, one connected to the LAN and one (ADSL) connected to
Internet. We have setup RRAS on ther Server to share ADSL
Internet connection. Now all PCs in my LAN can connect to
Internet. But we has problem, at one time only one PC can
connect to VPN server. When the second PC tried to
connect, It got the message: "Error 800: Unable to
establish VPN connection".

I don't where the problem come from: VPN server, our RRAS
server or clients.

All our client are running XP pro or W2K pro.

Thanks,

It could well be your ADSL router. Many SOHO routers will only allow one
VPN connection to be made through them.
