RE: default route problem

["Trey Nolen" <support internetpro net>]

On this same topic, Network Manager also removes any NON default routes that
you have.  I personally sometimes set different routes up for the internal
network.  These are NOT given out by DHCP, but when you connect/disconnect a
VPN, those routes are blown away.  I would LOVE for this to be addressed.
