I been trying to link up 2 networks between to VPN gateways and I have kind of given up, all the examples out there use a gif tunnel or a gre tunnel. I simply haven't been able to work out the routes or how to make ipsec-tools trigger based on seeing interesting traffic, its using a preshared key configuration. I have been using the typical ipsec.conf settings that most examples give for tunnel configurations but still no luck. At first I thought it was a NAT-T problem as the reason the IKE wasn't kicking in but after testing with pure internet IPs and no nat I realized it wasn't that. If I could just have an example to look at I think it could really help. Thanks Mike
