VPN access from behind router by 2 clients

[Guest]

Hi,

I have a windows 2k3 company network and I am having some trouble connecting
multiple VPN users from behind the same remote remote router.

2 laptops, used both in the office and at home (2 different user accounts).
At home is an ADSL router which we use to connect the laptops to the internet.
Either one can connect to the office network fine on its own, both laptops
can connect to the internet at the same time without any problems, but 1 will
not connect to the VPN if the other is already connected. The connection just
times out.

As far as I can see, everyone has the correct permissions, and the there are
plenty of available PPTP and L2TP ports to handle the incoming connections.

Can anyone point me in the right direction please.

It is probably a limitation of the router. Many SOHO routers will only
allow one VPN connection through.

Your SOHO router is probably using NAT, this limits the VPN connections to
one because you only have one public IP address. NAT can't translate the
different tunnels to two internal IP addresses.
