What's going on here is that dhclient is going through LPF rather  
than the socket API, and that apparently bypasses the firewall.   The  
ideal fix is to fix the socket API so that works with dhclient, but  
last time I promoted that solution I didn't get very far.   OTOH, I  
was in kind of a bad mood about it (it used to work), so possibly I  
was too annoying to be taken seriously.   I'm in the process of  
revisiting this for the new combined DHCPv6/DHCPv4 client.
