Test ikev2/double-nat-net
Description
The roadwarrior alice sitting behind the NAT router moon sets up a tunnel to the subnet hiding behind the NAT router sun. All IKE and ESP traffic directed to the router sun is forwarded to the VPN gateway bob using destination NAT. UDP encapsulation is used to traverse the NAT routers. leftfirewall=yes automatically inserts iptables-based firewall rules that let pass the tunneled traffic. In order to test the double NAT-ed IPsec tunnel alice pings the inner IP address of the router sun.
