I have fully working IPv4 network. I have static ip to internet, eth0 has it and internet connection is shared to lan by eth1. I have configured IPv6 addresses for both interfaces and IPv6 works to internet on my router.
I’m trying to run radvd to announce router for IPv6 but I can’t get it to start up. It complains that forwarding for ipv6 is disabled. I have modified /etc/sysconfig/sysctl with IPV6_FORWARD=“yes”
Still /proc/sys/net/ipv6/conf/all/forwarding has value of 0. I could echo it to 1, and get radvd up, but forwarding isn’t really up as data will not transferr.
How can I enable forwarding for IPv6?
