Yes this, works.
But, if you want to use your freebsd box as router to the ISP
you need aliasing, and this works in 2.2 out of the box.
Under 2.1.x you need a patch to ppp.
Furthermore gateway must be switched on in /etc/sysconfig, and
you have to configure your ed0 properly, so that your local
network runs via ed0, and your local PCs have addresses
like 192.168.x.x.
When you call your ISP the tun0 interface gets configured
dynamically with an IP address from your provider, and
packages are routed from your localnetwork to the internet
via tun0.
Look for 'iij-demand' or something else in /etc/ppp/ppp.conf
for demand dial on demand ppp.
