A very simple example would be to use the output of ifconfig ppp[0-3] or
tun{0-3] and seperate the assigned gateway from the assigned ip and write a
simple script using the results of fping or ping -c1 and sleeping the time
interval that you want.

You might want to set squid (/usr/ports/www/squid23 or 24 up as a proxy to take
advantage of the unused connections and bandwidth to fetch web pages, ftp, etc
for your internal network.

Provecho,
