Re: [tuntaposx-users] Use Tun/Tap as component for running only some services via OpenVpn

[Jonathan K. B. <jkb...@gm...>]

Tunnelblick doesn't "want everything running via VPN".

Tunnelblick is just a front-end for OpenVPN. It is the OpenVPN settings
that cause everything to be routed through the VPN (specifically, the
"route-gateway" OpenVPN option). Tunnelblick does have a checkbox that
causes this option to be used, but it is disabled by default.

If you don't control the VPN server, it may be that the VPN server is
"pushing" the route-gateway option to your client OpenVPN,  of course, in
which case I suppose you could create a "connected" script that un-does
some of the routing that is being forced on the OpenVPN client by the
OpenVPN server. Tunnelblick itself offers a lot of flexibility for
scripting (beyond what OpenVPN offers); see
https://code.google.com/p/tunnelblick/wiki/cUsingScripts.
