Just guessing but I'm thinking either a firewall (e.g. iptables) could
be blocking the traffic or the daemon is not listening to broadcasts,
i.e. compiled with --enable-use-sockets or similar.

Does it really say TCP there? That's a little strange for a DHCP server.
I'd expect it to have an entry for "raw" and one for "udp".
