Hello,
I have a few questions about Matter integration and IPv6 detection in Gladys.
Some time ago I changed my internal network and after some bad manipulations, I had to disable IPv6 forwarding from the WAN to the LAN.
So I only have internal IPv6 left (fe80:: ).
This caused an error in Gladys because we check whether the IPv6 is an external IP or not:
And since that day I can no longer access my Matter devices, nor matterbridge 
But it’s only with Gladys that I have no access because after some tests on Apple Home, Homey Self Hosted and HA, it worked very well: everything was detected, visible and functional.
Looking at the matterbridge docs, I saw this:
At the time of testing, I had noticed that if Gladys and matterbridge did not have the same IPv6 configuration (both had to be either internal or external, but not one internal and the other external), it had been decided to block internal IPv6 on Gladys. I realize that this was not such a good idea
@pierre-gilles do you think we can « reactivate » internal IPv6 on Gladys?
I’m available for testing
