- 패킷 리다이렉트 장치에서 패킷 필터링 장치로 사용자의 트랙픽을 리다이렉트하는 과정과,패킷 필터링 장치에서 입력된 패킷을 읽는 과정과,패킷을 분석하여 요청된 URL을 추출하는 과정과,패킷 필터링 장치가 읽은 패킷이 관리자가 지정한 차단 대상이 아닌 경우에 인터넷으로 패킷을 포워딩(Forwarding)하여 웹 서버가 사용자의 요청에 응답하는 과정과,패킷 필터링 장치가 읽은 패킷이 관리자가 지정한 차단 대상인 경우에 인터넷으로 패킷을 포워딩(Forwarding)하지 않고 드롭(Drop)시켜서 웹 서버에게 사용자의 요청이 가지 않도록 하는 과정과,사용자의 요청이 차단되었을 경우에 웹 서버로 사용자에게서 보내는 것과 같은 리세트(RESET) 패킷을 보내 네트워크 연결을 종료시키고, 사용자에게는 웹 서버가 보내는 것과 같은 차단 메시지와 연결 종료(FIN) 패킷을 보내 연결을 종료시켜서 사용자와 웹 서버가 이미 설정해 놓은 네트워크 연결을 해제하도록 하는 과정을 포함하여 이루어진 것에 있어서,상기 패킷 필터링 장치는 서버형으로 네트워크의 인터넷 접속지점에 설치되어 사용자의 웹 접속을 허용할 것인지 차단할 것인지를 결정하도록 구성하는 것을 특징으로 하는 비대칭 트래픽 흐름 방식을 이용한 웹 필터링 방법.
