racoon

I have a openvpn subnet 10.8.0.0/24 running one server and one client (laptop). openvpn works fine. Browsing the web over openvpn from the laptop works also fine.

Now on the server there is a private subnet with 10.7.8.128/28. The subnet is set up with racoon (IPSEC s2s vpn). The s2s vpn allows me to access the subnet 10.3.5.0/24 at the other s2s vpn end. Works all fine when I'm connected with ssh to my server.

From my laptop i can ping 10.7.8.129 (the servers ipsec local ip) but i cannot reach the net 10.3.5.0/24.

I tried to add a static route on my laptop 10.3.5.0/24 over gw 10.7.8.129 with no success.

Any ideas how i do setup the nat / routing?

Thanks
