Dear community,

I do have an issue that i cannot explain.

I do have 3 DECO M4 devices operational.

IF I use the main one - linked to the internet modem - in operational mode "router" AND i use my notebook that is assigned to a domain - youtube and facebook do not work.

if i am using nslookup somehow the domaine is added.

Example: www.youtube.com.domain.subdomain

The same is happening with facebook.

All the other sites i checked work correctly.

Then i changed the devices: the ones assigned to an domain have the same issue (only with youtube and facebook). Rest works.

I tried then to use the IPv6 adress - then it works - but why?! no idea.

So entering youtube-ui.l.google.com it works for the nslookup. To use the www.youtube.com - still does not work - also not in browswer - nowhere?!

If I do change now the operational mode to ACCESS POINT - all is working.

SO: WHY does the DECO M4 add the domain in router mode? Anyone has an idea please?
