DNS SERVER不通?卻可以上網及收信?

[chengmou]

真奇怪，小弟家裡的網路PING 任何地方(除了自己的IP之外)都是TIME UP，但卻可以上網收信，還可以解析網址? 真奇怪，找不到 DNS ，如何解析？真怪? 有人可以告訴我嗎?
THANKS.

ICMP被擋掉了

ICMP 應該是對方有FIREWALL擋掉，但我現在發現任何一個網址去PING 都是 timeout ??
真是奇怪....?是我這邊的問題?...

ping哪裡都不行..應該是你自己的電腦檔掉了吧..
防火牆?
不知道內建防火牆的IP分享器會不會檔到這種東西

不一定是對方, 假設你的防火牆不允許ICMP封包進出也會有同樣的結果. 你不妨試著PING自己LOCAL端的電腦看看

我 ping 自己 local的電腦...也ping 自己的真實ip，都是有 response...

不過我的分享器有簡單 firewall 功能..我把以下功能設定 enable了，但跟 ICMP應該無關才對的...

Firewall Option
Advanced Firewall Protection: Enable
Web Filter
Proxy: Allow
Java: Allow
ActiveX: Allow
Cookie: Allow

何不嘗試把Advanced Firewall Protection給Disable看看
