I'm totally baffled by how to get firewalld to forward IPv6 packets.
On my home network, every machine has a public IPv6 address (from
radvd). My ISP has IPv6. In between is a Fedora machine running
firewalld, but packets simply do not transition from one network
interface to the other.
If I ping ipv6.google.com from inside, I can see the packets as far as
the internal interface on the firewall, but they simply disappear. No
ICMP rejected messages or anything like that. If I ping an internal
machine from outside, I can see the packets at the external interface
of the firewall, but again they disappear into the aether.
I don't even know where to start looking. Any idea what to look for?
Uhm, try
$ sudo cat /proc/sys/net/ipv6/conf/all/forwarding
If it comes back as "0", you don't have IPV6 forwarding enabled. You
could (as root):
echo "1" >/proc/sys/net/ipv6/conf/all/forwarding
to enable it off immediately. You could add a rule file in /etc/sysctl.d
to set it for future boots. As root, create a file called
"/etc/sysctl.d/50-ipv6rules.conf" and put the following content in it:
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.default.forwarding = 1
That should enable IPV6 forwarding on future reboots.
