ip6tables - bug?

[coldwizard]

I think there is a bug with ip6tables

These two add statements should produce the same result.

ip6tables -A INPUT -i ! br0 -p tcp --syn -j DROP

ip6tables -A INPUT -i ! br0 -p tcp -m tcp --tcp-flags FIN,SYN,RST,ACK SYN -j DROP

But if you look at the resulting flags with the following, they are different

ip6tables -nvL INPUT

I am running firmware 3.0.0.4.374.42_0 on a N66U

Can someone please confirm the difference or if is it fixed with current version of the firmware?

Thanks
