What's in git as of a few minutes ago should work.

The standard vpnc-script from vpnc doesn't work on Solaris. There's one at which kind of works, but it requires you to configure your routing manually by editing the script -- it doesn't obey the routing information which it passed to it in the environment from vpnc/openconnect.

The script also needs to set the MTU on the interface according to the
$INTERNAL_IP4_MTU variable. On Linux, we do that manually with a
SIOCSIFMTU ioctl, to cope with older vpnc-scripts which don't do that.
Want to give me code which does the equivalent on SunOS?
