Since a dist-upgrade yesterday evening (running Debian Sid), NetworkManager appears to have stopped overwriting the default route set up through my local router once I connect to a VPN. Google indicates that this is intended, as most people apparently don't want to clobber their routes like that. I, however, would. How can I restore the old behavior?
Details: I have the VPN connection set up to be automatically established once the connection to my local net is there. It appears to be irrelevant if I configure the interfaces through DHCP or manually since at that point, a default route through my local router is needed.
Once the connection is finished, that default route persists, bypassing the VPN; thus, all connections made through it get blocked by my firewall which allows the physical interface for local traffic (almost) exclusively.
Once I issue ip route del default, the route through the VPN appears - I don't have to add it manually. This has to be repeated after every connection attempt. I tried messing with the ipv4.route-metric but apparently it's just ignored.
