VPN With 1 NIC - behind router

[Steven]

Hi there,

I have a Windows 2000 server with 1 NIC behind a router, but in the DMZ (for
testing purposes). I would like to allow VPN connections to the server, but
whenever I enable RRAS the server stops responding (pings timeout) to the
LAN.

Any ideas would be apprecaited

Thanks,

-Steven

When RRAS is configured as VPN, by default filters are added because of
which ping to the machine times out or doesnt respond. Added filters can be
seen in RRAS MMC console.

The problem isn't just with pings - the server stops responding to the LAN
entirely.

What I really want to know is: How do I setup a server to host VPN
connections with 1 NIC?

In the wizard, select remote access server. Accept the option to allow
VPN connections. This will set up the WAN miniports for VPN connections.
Test your server config by making a VPN connection from another LAN client.

When this is working, forward PPTP from your router to the LAN IP of the
server. Then try to connect through the Internet to the router's public IP.
The PPTP packets will be forwarded to the VPN server and you should be able
to connect. If you receive error 721, your router is probably blocking GRE.
GRE (IP protocol 47) must be able to pass through your router to allow the
VPN data in.
