Sorry, if I have missed it, but which system are these routing tables from? Bridge or LFW?

# uname -r
2.6.17-hardened-r1
# zgrep BRIDGE_NETFILTER /proc/config.gz
CONFIG_BRIDGE_NETFILTER=y

This means that you will be able to use IPTables to filter your bridged traffic. Which as I think about it, with out seeing your full IPTables rule set, may be the reason some of your packets are having their state incorrectly identified. Can we see a full iptables-save output?
