Go to the Split DNS wiki article and read that, you can also check your DNS configuration by running all the commands in the "Verify...." section of that article. If you still have problems then post the output from those commands here.

BTW, do not post duplicate messages in the forums even if it's in a different language, pick a suitable forum and then post one message and wait for an answer. Yes, English is the most likely one to get you a response.
