NAT or PAT translation over the VPN tunnel. When accessing the remote network
192.168.100.x, the hosts 10.0.0.3 and 10.0.04 will not be translated, and hosts in
the remote network 192.168.100.x can access the hosts 10.0.0.3 and 10.0.04
directly.
The client hosts are given IP addresses that are fully routable by the destination
network over the tunnel. These IP addresses could be either in the same subnet
space as the destination network or in separate subnets, assuming that the
destination routers are configured to properly route those IP addresses over the
tunnel.
