Send these pings using the Internet Control Message Protocol (ICMP) or TCP to one or any of the devices you believe to be involved. In some cases if ICMP is filtered, you can usually switch to TCP (Transmission Control Protocol) and use tcping, telnet, or another TCP-based method to check for reachability.
