Hi

Does anyone have any experience of setting up a Gateway to Gateway VPN?

I am trying to do this using Netgear Routers over BT Broadband and can't understand why its so flakey?

Any pointers appreciated!

Does it work and then drop, or does the connection just do nothing and fail at the authentication stage.

You'd need endpoints surely?

It has worked. Basically I'll press the connect button, and it will establish a tunnel, but then I'm not sure what to do.

The next morning when I come to figure out what to do next the tunnel will be closed, and it will not reconnect no matter what I do.

The endpoint can be any PC on the LAN, apparently.

I follwed this document here http://kbserver.netgear.com/kb_web_files/n101569.asp but I'm beginning to think BT Broadband could be the culprit, is this likely?

Site-2-Site links require that the PCs in each site be able to route traffic to each other. You will need to define two IP sub nets and enter there addresses onto the router tables on the netgear(VPN gateways). The default gateway must then be pointed to the Internet or you will lose web traffic. You should now be able to ping the ip numbers of the machines in remote sub nets if the tunnel is working correctly. -DNS is beyond the scope of this for now.-

The tunnel works one day and not the next is most likley caused by Dynamic IP addresses (DHCP) on the netgear public port. This means the ISP is changing the IP number every day and changing the location of the tunnel end points, IPSEC will have a kitten with this. Ask BT about purchasing a static IP number - $$$

Hope this helps
