Hello, now I have spent many hours to configure openswan for VPN connections without any success. My goal: VPN Server CentOS 6 with public IPv4 VPN Client (= road warrier) from private site with NAT router or from mobile cell with Linux, Windows 7, Mac, iPhone or Android Is there any how to in the net? When I read file:///usr/share/doc/openswan-doc-2.6.32/config.html then I belive, there is no solution. It is written, that I have to reconfigure the NAT router of the mobile provider or the hardware NAT router of the private dsl uplink. Both is impossible. Thank you for help in advance.
