[TriLUG] openvpn questions

[Alan Porter]

> I can ping both 10.8.0.1 and 10.8.0.6 from both client and server, but 
> not 10.8.0.2 or 10.8.0.5. What are these unpingable addresses about?


Openvpn works by making point-to-point connections to the clients, and 
then routing packets within the openvpn process. So you have set up 
endpoints on .1 and .6 . The .2 and .5 addresses are used internally by 
the openvpn process.

I am not sure whether these addresses should be pingable or not. But it 
took me a long time to figure out why I always had twice the number of 
IP addresses in use than I would expect.
