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. Now for Christmas dinner!
