I have already successfully setup a connection from my main home server to
the VPN setup by the hosting company of one my clients and have configured
it to be routable from all hosts on my home LAN (the LAN is 192.168.11.0/24
and the VPN is 10.31.10.0/24).

I want to find a good free VPN that allows connection to the wider Internet
and configure it the same way.   Where do I start and which VPN is best?
