Enabling conntrack_be_liberal seems to have solved the issue for me.



echo "1" > /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_be_liberal

seems to work for my systems. No more INVALID packets.

Some of the netfilter firewall how-to guides I've found say that ip_conntrack_tcp_be_liberal should never be set on a firewall. So I'm still left wondering if I'm working around a bug and my firewall is not as strict as it should be, or are these how-to's all wrong.
