pfSense

Hi

I was playing around with IPv6 configuration for a bit and seem to have triggered an issue with the radvd config file generator script. Since some of these steps happened a while ago I am not sure that I remember everything correctly but here is what I think happened:

• I created a manual radvd configuration for my LAN interface.
• I switched the interface to instead follow the WAN interface and use prefix delegation to configure IPv6
• pfSense's services.inc script generated my radvd.conf. Seeing how there was a (unused) "router" configuration for my LAN interface, the template from lines 175-179 was used. The dupe check on line 302 then prevented the correct entry to be generated. The main difference was that the generated entry said "AdvSendAdvert off" rather than "on".

I would recommend checking whether the radvd configuration is active at all before using it, especially since the web interface does not allow the user to change / remove the configuration when the interface is in "Track interface" mode.
