Ok, I have fixed it! :) I put in an explicit iptables rule for dport=bootps and protocol=udp and it all sprang into life. Anyone know why the rule -A block -s 192.168.0.0/255.255.0.0 -j ACCEPT was not sufficient? It works for all the other protocols. Thanks to everyone who responded, particularly Guennadi who got my brain turning over.
