Here's an example:

gateway:~ # shorewall compile -C perl firewall
Compiling...
Shorewall configuration compiled to /root/firewall
gateway:~ # time ./firewall restart
Restarting Shorewall....
done.

gateway:~ # shorewall compile -C shell firewall
Compiling...
Shorewall configuration compiled to /root/firewall
gateway:~ # time ./firewall restart
Restarting Shorewall....
done.

And with Shorewall-perl, the netfilter rulesets are swapped atomically
on a table by table basis. So there are no periods when packets are
being dropped.
