神马品牌网计算机弹奏最炫民族风:tracert命令在很多ADSL路由器后边不太好使,为什么?

当我的ADSL路由器是D-Link时,可以使用tracert命令,大部分路由都能正常显示,如果用的是tplink或者是其他的路由器,总是显示time out.
C:\Documents and Settings\燕子>tracert 202.108.13.131
Tracing route to www.danawa.com.cn [202.108.13.131]
over a maximum of 30 hops:
1 * * * Request timed out.
2 * * * Request timed out.
3 * * * Request timed out.
4 * * * Request timed out.
5 * * * Request timed out.
6 * * * Request timed out.

Trace complete.

原因是路由器防火墙的安全规则默认屏蔽了这种探测，或者根本就不支持这种探测行为。
我使用ADSLModem做路由，里面的ip包过滤功能就可以随意更改是否允许内网使用tracert命令探测。
