Hello, Freebsd-net.

 Typical task: two "home-grade" ISPs, one router. Need to monitor both
channels, switch default route, balance outgoing traffic, manage ipfw
firewall, etc.

 For Linux here is Net::ISP::Balance
 (http://lstein.github.io/Net-ISP-Balance/) and LSM as part of it
 (http://lsm.foobar.fi/download/), but they are very Linux-specific.

 Maybe, somebody have good set of such scripts?

 Looks like /sbin/dhclient-script should be rewritten too, for example,
 because standard one uses "default interface" detection which fails in race
 condition of two ISPs (both uses DHCP!), for example.
