네임서버 설치에 어려움을 격고 있습니다.

네임서버를 설치하고 셋팅하였습니다.
서버내부에서는 ping,nslookup,host 로 나오는데 외부에서는 안되네요.
하루가 지났지만 그래두 안됩니다.
원본소스가 좀 길지만 좀 봐주세요.
인터넷진흥원에서 DNS를 점검한결과
--------------------------------------------------------------------------------
각 네임서버에 기록된 네임서버 정보 : 조회 대상 서버 : < ns1.kkcu.or.kr.>
네임서버가 모두 DNS SW를 운영 : DNS SW 운영를 운영하고 있는 네임서버가 없습니다
--------------------------------------------------------------------------------
이런 결과가 나왔네요.뭐가 문제인지 모르겠습니다.
