내 Firefox가 vps 서버에서 전달된 localhost:9099 프록시를 사용하도록 하려고 하는데 왜 이렇게 작동하지 않습니까? 나는 항상 얻는다bind: Address already in use

$ ssh -vfND 127.0.0.2:9099 vpn 
OpenSSH_5.9p1, OpenSSL 1.0.0j-fips 10 May 2012

문제 해결의 다음 단계를 추가했습니다. 중복 바인딩이 해결되었습니다. 로컬 컴퓨터의 방화벽 문제였으므로 이제 vps 서버에 연결할 수 있습니다. 하지만 브라우저에서 http를 열면 브라우저의 프록시가 여전히 작동하지 않습니다.

The connection was reset The connection to the server was reset while the page was loading. If your computer or network is protected by a firewall or proxy, make sure  that Firefox is permitted to access the Web.
