Decomposed scenarios

Decomposed Scenario A: Site-to-Site tunnel with static public IP address

In this scenario, both sites have static public IP address and setup a tunnel between sites. After the tunnel is established, the clients within the site should be able to ping the clients on the other side through the tunnel. The tunnel is authenticated through pre-shared key.

...

Scenario Description:

Tunnel between site A and site B
Suppose there are two sites A and B. A comes with the subnet 10.1.0.1/24, B comes with the subnet 10.2.0.1/24
Gateway for A is 192.168.1.10
Gateway for B is 192.168.1.11
A and B would like to establish a tunnel
10.1.0.1/24 == 10.2.0.1/24

Decomposed Scenario B: Host-to-Site

...

tunnel when the initiator requests an overlay IP

In this scenario, the initiator sends out a request to the responderthe responder(either a site gateway/remote host) which has a static public ip address(or dynamic pubic IP with static domain name) in order to setup a tunnel between. However, this time, the roadwarrior is also going to ask for a virtual IP that assigned by the responder. After the tunnel is established, the roadwarrior should be able to get an overlay IP and ping the clients on the other side through the tunnel. The tunnel is authenticated through pre-shared key.

Scenario Description:

Tunnel between site A and host B(Responder and Initiator)
Suppose there is one site A and one host B. A comes with the subnet 10.1.0.1/24.
Gateway for A is 192.168.1.10 which is a public ip address
Host B has no public address and want to request one from the peer(suppose the vip assigned is 10.3.0.12)
A and B would like to establish a tunnel
10.1.0.1/24 == 10.3.0.12/32

Suppose there are two hosts A and B.
A has a public ip which is 192.168.3.1
B is a host which already get a vip 10.3.0.12
A and B would like to establish a tunnel
