全无回应包．怪事！

现在我无法.在本机上做ＨＴ.ＴＰ的请求，其它应用正常，不知道是怎么回事．.

已经排除了防火墙有可能引起的问题．

再详细的介绍下环境吧

这台机子是一个内网的网关来的,上面有起用squid.

ＬＡＮ--------------GATEWAY-----------------------------INTERNET
                            squid:tcp/8080

现在内网用户无法使用ＳＱＵＩＤ代理上外网，可以访问内网里的网站，以为是ＤＮＳ问题，但可以ＰＩＮＧ域名，ＮＳＬＯＯＫＵＰ外网．内网用户跳过ＳＱＵＩＤ代理就可以上网站．
所以通过tcpdump抓包，得到上面的结果，所有的http request出去都没有返回结果．
哪位能看出个什么名堂来吗

本地能看到listen这个口了么？本地telnet可以么？

>>>本地能看到listen这个口了么？本地telnet可以么？

不清楚你说的listen哪个口，本地telnet哪里？squid port?如是telnet  8080口的话是可以的．

现在的问题是，本机去ＨＴＴＰ请求的话就没有回应，但内网的机子通过它出去ＨＴＴＰ请求的却可以（不用ＳＱＵＩＤ代理的话）．
