Sample scenario showing VPNClient and VPNServer service configuration.
This topology features an OpenVPN client and server for virtual private
networking. The client can access the private 10.0.6.0/24 network via the VPN
server. First wait until routing converges in the center routers (try using the
Adjacency Widget and wait for blue lines, meaning full adjacencies), then open
a shell on the vpnclient and try pinging the private address of the vpnserver:
vpnclient> ping 10.0.6.1
You can also access the other 10.0.6.* hosts behind the server. Try running
tcpudmp on one of the center routers, e.g. the n2 eth1/10.0.5.2 interface, and
you'll see UDP packets with TLS encrypted data instead of ICMP packets.
Keys are included as extra files in the VPNClient and VPNServer service
configuration.
