So, can anyone suggest what I should do with packets that have a
source address of 0.0.0.0?
Junk them -- they have no real business on your network, as 0.0.0.0
isn't a valid assigned address on the live Internet.
Except at least when you use DHCP on your network. DHCP clients use
0.0.0.0 as a source address when issuing DHCP requests until they get a
regular address from the server.
Heh. That wont help: you can't assign 0.0.0.0 to an interface in Linux,
so the DHCP client uses a "packet socket" -- reading direct from the
interface, bypassing the firewall.
That sounds consistant. But what about the DHCP server side ?
