I am trying to configure a gateway-to-gateway IPSec VPN between a Netopia 3340 broadband router and a Cisco Pix 501 firewall (ver 6.3) using pre-shared keys. I have made what I think are the necessary configuration changes on both ends but cannot get the tunnel to set up. The Netopia setup is very simple and I am fairly certain it is correct. I believe the problem is on the Cisco side. I suspect this because when I ping from the local (cisco) network (192.168.16.X) to the remote (netopia) network, (192.168.1.X), the ISP gateway router returns "destination host unreachable". Performing the same ping test from the netopia side (192.168.1.X) to the cisco side (192.168.60.x), I get "request timed out" responses. It seems to me if the tunnel was up, the non-routable addresses going from the cisco to the netopia would pass through correctly and I would not get the unreachable error.
I have attached a file with both configurations. for the Pix 501, I have highlighted the changes I made to the existing configuration file. Local public IPs are shown as XXX.XXX.XXX.XXX. Remote peer public IP is shown as YYY.YYY.YYY.192. Thanks for your help.
