An IPv6 ESP tunnel connection between the gateways <b>moon</b> and <b>sun</b> is successfully set up.
|
||||||
|
It connects the two IPv4 subnets hiding behind their respective gateways. The authentication is based on
|
||||||
|
X.509 certificates. In order to test the IPv4-over-IPv6 ESP tunnel, client <b>alice</b> behind <b>moon</b>
|
||||||
|
sends an IPv4 ICMP request to client <b>bob</b> behind <b>sun</b> using the ping command.

It connects the two subnets hiding behind their respective gateways. The authentication is based on

In order to test both the net-to-net tunnel and the firewall rules, client <b>alice</b> behind <b>moon</b>

sends an IPv6 ICMP request to client <b>bob</b> behind <b>sun</b> using the ping6 command.
