OK, firewall rules aren't in my wheelhouse. I've got an IPv6 network with a /56 prefix assigned to me by my ISP. This, I understand, is rather large and it breaks some functionality. It is meant that this be broken up into 256 /64 networks or smaller.
On my ISP facing router the LAN has a /64 segment defined and all systems on the same LAN work just fine. I created a static route to a host with 2 LAN interfaces. It can be reached by using either IP address. I have made these additions net.ipv6.conf.all.forwarding = 1 net.ipv6.conf.all.proxy_ndp = 1 to a config file in /etc/sysctl.d However in order to reach that second system from the internet I need to disable the firewall on the first. Otherwise I get....
