범위 지정 가능하지 않을까요? 방화벽 룰에서 처럼 예를들어 10.1.1.0/25는
10.1.1.0~10.1.1.128일 겁니다.
 아래는 DEMARC에서 복사한 테이블 입니다. 테스트 해보세요~

   : 그중에서 httpd.conf 파일에서 여러가지 Allow, deny 도 있긴한데
: 그랬더니 막히긴 하는데, 일일히 ip address 를 다 적어줘야 하는건가요?
: 예를 들면
:
: 10.1.1.1~ 10.1.1.30 번까지는 허용해주고 나머지는 못들어오게 하고싶다면
:
: 이런경우는 번호를 무려 30개나 써줘야 하는데 그렇게 하는게 맞는건가요?
: 아니면 다른 와일드 카드 같은 문자로 해결할수 있나요? 특정 게이트 웨이
: 밑에 있는것도 아니고 달랑 30개정도만 해결하고 싶습니다.
:
: 알고계시면 답변좀 해주세요...

: 그럼
