I thought i'd drop this info here for others. To allow all IPv6 traffic without Firewalling, add the following to your WAN-UP script: Code: # Disable IPv6 firewall # ip6tables -P INPUT ACCEPT ## Opening this will let anyone on the internet have access to the router itself. ip6tables -P OUTPUT ACCEPT ip6tables -P FORWARD ACCEPT My goal was to have totally open IPv6 addresses to all computers on my LAN. My stats: Shibby Tomato v119. "MIPSR2-119 K26 USB Big-VPN" on a Linksys WRT610N v2. Comcast, with native IPv6 dualstack.
