标题Re: [问题] 加了firewall 有少部分网站上不去
时间Mon Jun 28 19:04:50 2010
※ 引述《zaknafein (zak)》之铭言:
: 今天在我电脑与ISP线路间加了一台 PIX 506
: 可以正常拨号上网,但是有些网站却上不去!
: 像是 fdzone, miroko 等等
: 我的 firewall access-list 完全没有设,
: (configuration除了pppoe, nat, global 其他都没了)
: 小弟做了个实验,
: 就是若不透过firewall,由我自己的主机拨号上网,这些网站又都OK...
: 请问各位大德这会是怎样的原因呢?
