First Post. I am currently using tomato-K26-1.28.pre9055MIPSR1-beta-able-MiniIPv6 on a Buffalo WHR-G125. This is very stable at present. I am using an he tunnel for ipv6.
I have run nmap, as Zenmap, against the router. Four expected ports are open without adding ipv6 firewall rules.
Adding the rules, as found elsewhere in this forum, five ports are open, a safe superset of the previous.
So do I need to add the rules? Superficially, it would seem not.
