服务器有两块网卡 eth0 192.168.0.100 255.255.255.0 eth1 192.168.0.1  255.255.255.0 手动设定ip 并且做了基于ip的虚拟主机 dns 服务器为202.101.172.35 202.101.172.47 服务器刚挪过位置之前说是可以Ping 通外网
服务器可以Ping通局域网网关（192.168.0.1）但Ping不通外网（例如 ping www.sina.com）也访问不了外网

使用mii-tool显示link ok
用traceroute 命令也不能成功

操作如下
gentenforce
disabled

iptables -L -n (没有策略）
iptables -F
service iptables stop
service network restart
ping www.sina.com(不成功） ping 外网ip也不行  ping 8.8.8.8 也不行
