I have two different subnets set up on my network (say 10.10.10.* and 10.10.12.*). I am having difficulty pinging a D-Link access point (was a router, now configured to be an AP) located on subnet 1 from subnet 2. However, I can ping other computers on the network. Here is a breakdown:
10.10.10.5 -- Desktop Computer
10.10.12.4 -- Access Point 1 (D-Link)
10.10.12.3 -- Access Point 2 (Linksys)
10.10.12.6 -- Laptop Computer connected to either AP1 or AP2
ping from -> to
10.10.10.5 -> 10.10.12.4 No Go
10.10.10.5 -> 10.10.12.3 Works
10.10.12.6 -> 10.10.12.4 Works
Interestingly enough, the D-Link AP works fine aside from not being ping-able. I can connect to it, access internet from it, and ping other network computers while connected to it; I just can't ping the AP from outside the subnet.
Any ideas why this might be? What sort of things should I test?
