FTP와 TELNET이 안됩니다.

방화벽 설치한 상태고요 FTP는 방화벽에 통과가능하도록 선택해서 설치했습니다.

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

그런데 로컬에서 ftp 로긴하면

220 localhost.localdomain FTP server (Version 5.60) ready.

334 Using authentication type GSSAPI; ADAT must follow

530 Must perform authentication before identifying USER.

Login failed.

이라고 나오고요 외부에서 ftp 로긴하면

530 Must perform authentication before identifying USER.

라고 나옵니다.

그리고 TELNET은 로컬에서는 로긴이 잘되는데요 외부에서는 아무것도 안됩니다.
