VPN COncentrator 3005 site tunnels routing

[richardtye]

I have a PIX 501 in Denmark. A VPN concentrator in the UK and the US.

I have a LAN IPSEC tunnel from the UK to Denmark and from the UK to the USA.

From the UK I can connect to Denmark and to the USA, but I cannot connect from Denmark to the USA (via the UK).

What do I need to do to route accross the tunnels that have been created in the UK to allow the traffic to route between Denmark and the USA.

The following documents will help you in configuring LAN to LAN Tunnels on a VPN Concentrator.

Thanks for the information, but the links only show a 1 to 1 tunnel. I need to understand the scenario where I have three devices. Device 1 is a PIX, device 2 and 3 are VPN concentrators. I need to route tunneled traffic from device 1 to device 3 via device 2. At the moment device 1 and 2 can communicate, and device 2 and 3 can communicate, but device 1 cannot communicate to device 3 via the tunnels.

The tunnels are between device 1 and 2, and between device 2 and 3. I do not want to have to create a separate tunnel from 1 to 3, because this explanation here, is a simplification of a much larger network.
