VPN setup

Hi,

 

I'm working on setting up a VPN to a server we host in our office.

 

Our setup is a BT Home Hub 3 connected to a Dell Sonicwall Firewall which is connected to our VPN and other networked computers.

 

I can connect to the VPN when on the same network, so it makes me believe the Hub or the Sonicwall are stopping it because I don't need to go through them to get to the VPN.

 

So because external connections would need to go through the Hub then the Sonicwall, I would need to set up the Hub to port forward as well as the Sonicwall?

 

The first issue I encountered was when I was selecting the device for port forwarding it wouldn't allow me to use the IP address of the Sonicwall, I could only select the only connected unknown device (Because it's the only device connected via ethernet I was able tell it was the Sonicwall)

 

So I then allowed 1723 TCP forwarding on the hub, but I've also read about GRE protocol 47, but not sure how to set the GRE?

 

Once I have the Hub figured out, it's on to the Sonicwall.

 

Thanks

Tom

I've just noticed that the BT hub is on a different LAN IP to the VPN.

 

The BT subnet is 192.168.1.254 and the sonicwall uses 192.168.168.168. The VPN would had been given an LAN IP by the Sonicwall, thus I cant find the VPN by IP on the Hub.

 

So now what...?
