[arch-general] Default route not restored (deleted?) after VPN - Juniper Network Connect

[Qadri]

Hi all,

I've regularly used a VPN to access my school network. I use Juniper ncsvc
to connect. It is worked into a script such that I can just call it, and
then C-c to stop the VPN.

Previously, the default route would be restored after I killed the VPN
connection, so I could close the vpn connection and resume my internet use
without thought. Now, I need to restart networkmanager (or that's the
quickest/dumbest way I could mindlessly think of) to restore the connection
(see output below). What has changed this behavior, and what methods can I
take to getting the old behavior back?

Thanks,
MAQ.
