So every traffic is no problem but i cant resolve the hostnames of pc clients on branch offices from the main office.

I created a forwarded dns zone in the main branch and pointed it to a router in a branch.

ks . domain . intranet = 192 . 168 . 20 . 1

Test client becomes ks-pc1 . ks . domain . intranet.

In the branch i can resolve it but not from the main branch.

From branches i can resolve names from main office cause i set the dns as their default.

So the dns in main cant get information from the branch router but i dont know why and cant find approperiate settings in the sdn controller.

Any hint where im thinking wrong?
