Save to file, chmod +x name-of-file, don't run this script from cron.
It needs to be started at boot time, or before you make a VPN

HTH,
Corrected code follows (missing do/done).
Save to file, chmod +x name-of-file, don't run this script from
cron.
It needs to be started at boot time, or before you make a VPN
connection.
