Costa,

I think that zones are more of a "I am now on a public wireless LAN",
"I am now on my home WLAN", "I am now on my work LAN" and so my trust
varies within a single interface kind of thing.

Rick, firehol scripts can alread have conditionals, so provided the
firewall can be triggered to restart on network change and with the
appropriate zone passed in, it should already be possible.

A lightweight alternative where all rules are loaded in netfilter and
changes the behaviour happen in response to an external event without
a restart would be more difficult. Custom actions or something similar
might be able to help?
