私のFirefoxにvpsサーバーから渡されたlocalhost:9099プロキシを使用させようとしていますが、なぜこれがうまくいかないのですか?いつも手に入れるbind: Address already in use
$ ssh -vfND 127.0.0.2:9099 vpn
OpenSSH_5.9p1, OpenSSL 1.0.0j-fips 10 May 2012
debug1: Connection established.
debug1: Host is known and matches the RSA host key.

debug1: Local forwarding listening on 127.0.0.2 port 9099.
bind: Address already in use

debug1: forking to background
トラブルシューティングの次の手順を追加しました。重複バインディングが修正されました。ローカルコンピュータのファイアウォールの問題だったので、vpsサーバーに接続できるようになりました。しかし、ブラウザでhttpを開くと、ブラウザのプロキシはまだ機能しません。
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.
