I have a XG setup as a transparent firewall, bridging PortA and PortB. I recently configured IPv6 on the bridge interface, and it does not work when configured via the GUI.
The interface has the configured static IP, but cannot reach IPv6 addresses, nor is its address reachable from the network.
The dmesg indicates IPv6 is disabled on the bridge:
[ 32.720234] IPv6: Bridge1: IPv6 being disabled!
When I check /proc indeed IPv6 is disabled.

Manually setting that parameter to 0 allows IPv6 traffic to function.

Have I missed a configuration option somewhere, or is this a bug?
