Can this be made a bit more robust? An easy DoS would be to offer to
be a gateway, but not run DHCP. All my near neighbours then fail to
get an IP address and i have quiet network with more bandwidth for
myself.
Could we inspect the DHCP packet a bit more deeply, look for DHCP
discovery packets, unicast 3 in 4 to the best gateway, broadcast 1 in
4 as a fallback.
