故障现象：
网吧用户有多个外网IP地址，其中拿一个地址来做游戏私服，环境已搭建好；外网用户都可以正常登录游戏私服，唯独内网PC不能正常登录。
排错过程：
1、在自己的电脑上ping 用户私服地址：
C:\Documents and Settings\Administrator>ping 222.240.240.142
Pinging 222.240.240.142 with 32 bytes of data:
Reply from 222.240.240.142: bytes=32 time=195ms TTL=114
Reply from 222.240.240.142: bytes=32 time=200ms TTL=114
Reply from 222.240.240.142: bytes=32 time=204ms TTL=114
Reply from 222.240.240.142: bytes=32 time=195ms TTL=114
Ping statistics for 222.240.240.142:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 195ms, Maximum = 204ms, Average = 198ms
可以ping通，说明此服务器运营正常。
2、telnet 登入用户路由器，ping 私服地址：
hiper% ping 222.240.240.142
PING 222.240.240.142 (222.240.240.142) with 64 bytes (56 data):
--- ping 222.240.240.142 statistics summary ---
8 packets sent, 0 packets received, 100% packet loss
Ping不通，查看ARP表：
Hiper% sh ip arp
222.240.240.142 ?????pending????? Pending 1:ie1 1 600
要来用户私服MAC地址，在高级配置àIP/MAC绑定中搜索，发现此MAC被绑定为内网一IP，删除后再ping：
hiper% ping 222.240.240.142
PING 222.240.240.142 (222.240.240.142) with 64 bytes (56 data):
Reply 64 bytes (56 data) from 222.240.240.142: seq=0 ttl=128 time=0 ms
Reply 64 bytes (56 data) from 222.240.240.142: seq=1 ttl=128 time=0 ms
Reply 64 bytes (56 data) from 222.240.240.142: seq=2 ttl=128 time=0 ms
Reply 64 bytes (56 data) from 222.240.240.142: seq=3 ttl=128 time=0 ms
Hiper% sh ip arp
222.240.240.142 00:e0:a0:15:05:80 Dynamic 1:ie1 30 575
用户内网PC可正常登录游戏私服。
结论：该用户首先将游戏私服配置一内网地址并做了IP/MAC绑定，后来又将其IP地址配置为公网地址，这样导致内网用户只认其内网地址，此时登录路由删除其绑定的内网地址即可正常通讯。
