Manually adding it back works, thanks you!  But how do I know the VPN
gateway (as VPNGATEWAY in the vpnc script) in general?  For now I shall
simply kill/start openconnect in the network start/shutdown script,
which is fine.  But when roaming (eg when the laptop resumes from RAM
and automatically reconnects to a different wireless network), I hope
openconnect could detect connection loss and call the vpnc script to
reset and then set the routes?
