When testing in my lab, I ran into some weird behavior with ping. I had 2 win8 machines attached to a switch, and that switch attached to a router. I was unable to ping from one of the PCs to the other one, but found that both the router and switch were able to ping both machines without problem.
Then I added a inbound firewall exception for ICMP on both PCs and was able to then ping PC to PC.
I understand that the Windows firewall blocks pings by default, but does anyone have any thoughts on why it wouldn't block them from the router or switch.
Hardware I'm using is as follows:
Win 8 HP laptop
Win 8 tower
Cisco 3550 switch
Cisco 2950 switch
Cisco 1721 router
