本文探讨了在InWRT54G设备上如何轻松禁用PING功能，并指出在VEFSX41设备中无法直接实现该功能。由于PING使用的是ICMP协议而非TCP或UDP，因此不能通过常规的端口封锁方式来阻止PING请求。

In WRT54G, we can easily disable PING through Access Restrictions which is build-in.

But in VEFSX41, we can't do that. It just supports TCP or | and UDP. while

"Ping doesn't use TCP or UDP, so there is no "port" number associated with

it.  Ping uses ICMP, a separate protocol layered on top of <nobr>IP</nobr>.  So you can't

ping an application, you can only ping the <nobr>network</nobr>stack (it is what

responds to true pings)."

I have no ideas for that :(
