[gentoo-user] [OT] Pinging two devices on the same IP address

[Mick]

Hi All,

I am trying to troubleshoot two devices both behind the same IP address:

Device A:  a router
Device B:  a wireless access point

The network looks like this:

Internet >> modem >> router >> AP

Currently I have set up a firewall rule in the router to forward all pings to 
the AP.  The logic is that if the ping returns then both router and AP are 
up.

That's alright when both devices are working.  However, if I am interested to 
know which one of the two has failed, a different system is needed.  Any idea 
how I could ping them both separately?  Is there a clever firewall rule I 
could concoct?
