我的系統是 Linux, eth0是內網, eth1是外網.
我用 ping的方式, dns server, 目的ip都是通的
[root@localhost ~]# ping 168.95.192.1
PING 168.95.192.1 (168.95.192.1) 56(84) bytes of data.
64 bytes from 168.95.192.1: icmp_seq=1 ttl=248 time=37.7 ms
64 bytes from 168.95.192.1: icmp_seq=2 ttl=248 time=37.4 ms
[root@localhost ~]# ping 64.233.183.104 (www.google.com.tw)
PING 64.233.183.104 (64.233.183.104) 56(84) bytes of data.
64 bytes from 64.233.183.104: icmp_seq=1 ttl=53 time=39.8 ms
64 bytes from 64.233.183.104: icmp_seq=2 ttl=53 time=39.5 ms
不過我直接ping www.google.com.tw就是沒有反應.....
我想應該是轉譯的問題...
但是系統的設定看似乎都是對的, routing table也沒什麼問題...
哪位大大幫忙診斷一下~~XD
