Hallo, I'm looking for a designated way to disable ipv6 routing because WAN (vlan2) and LAN are bridged if ipv6 is used in order to provide ipv6 to computers on LAN. Code: ebtables -t broute -A BROUTING -i $WAN_IF -p ! ipv6 -j DROP Idea based on: http://www.linksysinfo.org/index.php?threads/customizing-tomato-with-ipv6-bridge.24238/ http://blog.loetzimmer.de/2015/02/bridged-ipv6routed-ipv4.html https://www.dd-wrt.com/phpBB2/viewtopic.php?p=1062388 The tomato router should also accept RA to receive an ipv6 address to reach ipv6 destinations itself e.g. public ipv6 dns servers. Accepting RA only works if ipv6 routing (forwarding) is disabled. In this bridged scenario ipv6 routing is not used therefore it can be disabled, but how? Putting Code: echo 0 > /proc/sys/net/ipv6/conf/all/forwarding into WAN up script ends in Code: cat /proc/sys/net/ipv6/conf/all/forwarding 1 after boot finishes. Any hints, suggestions and tips are welcome.
