re [KLUG Members] OpenVPN & DHCP

[Michael Lueck]

I am not sure if it was part of OpenVPN's samples or what, but we run a 10.
Class A network here with a Class C per site. The OpenVPN uses a 172. network.

Ours is configured hub and spoke style where all sites come back to the main
site. Thus the requirement be simply that the two end points always have unique
addresses on the 172. network, and life is good.

You COULD think of it that the 172. network is the one that virtually ties all
of the 10. real networks together. In theory 172. is a sort of cloud in picture
sense, and bridges remote site 10. class C's with the home site 10. class C.

For sanity I would select something totally different for the VPN internal
numbers than the networks you are connecting. Admin life is hard enough, keep
some "numbering standards" differences between the two for your sanity.

Best I can do with words and not marker boards! ;-)
