BR200 bug with IPv6 and Auto Detect takes all ports offline

Dear Community,

I found a bug on the BR200 if IPv6 is enabled for WAN and set to Auto Detect (router is taken offline for more than 5 seconds everytime a DHCP lease extension arrives (in my case every 15min).

The problem is described in detail here:

I'm unable to file a bug report (no more technical support on the product), please let me know how to proceed.

Thanks and best regards
