VPN/RRAS issues - help please!

[Haggisman]

Wasn't sure if maybe this should go in servers/enterprise?

Basically I started in a new position a couple of months ago, in charge of... well... everything at a small business.

Unfortunately last night one of our routers died (maybe the heat or just old age), killing our only VPN connection. So today I've spent most of the morning setting up a new server with VPN so we have a backup just in case it happens again.

I'm having some major problems - I've got the relevant ports forward on the router (1723, 500 and the GRE protocol), and users are able to connect to the server, but once they are connected they can't see/connect to/ping anything on the network.

The server is on a domain, running 2008 R2, with RRAS installed.

There are 2 network interfaces;

The router has the IP of X.X.X.3

NIC 1 is connected to the internal LAN and has the following settings:

IP: X.X.X.51
Mask: 255.255.255.0
No gateway

DNS 1: X.X.X.11 (our internal DNS server)
DNS 2: X.X.X.1 (main internet router)

NIC 2 is connected directly to the router and has the following settings:

IP X.X.X.52
Mask: 255.255.255.0
Gateway: X.X.X.3

DNS 1: X.X.X.11 (our internal DNS server)
DNS 2: X.X.X.3

I'm sure I'm missing something obvious, but any pointers would be brilliant =)

Cheers guys!

Woo! I managed to solve it. For some reason, the new RRAS server had IP filtering set up on the VPN interface, to only allow traffic between the server and router. No idea why or how, but I've now reconfigured the filters and everything is working as required
