How about keeping netfilter enabled and adding logging rules to various
netfilter tables, to see how far the packet (or the potential response)
gets?

iptables -I PREROUTING -t raw -p tcp --dport 80 --syn -j LOG
--log-prefix "raw-prerouting: "

and the same for mangle-prerouting, mangle-input, nat-prerouting,
filter-input. This could help pinpoint at which layer the packet gets lost.
