Lost PING to APs from other subnet after ZD1100 was replaced and with other
ZD1100 with newer firmware
We have recently replaced our ZD1100 with another ZD1100 as the original failed. I have then restored the orginal wireless configuration to the new ZD1100 and configured the rest manually. The APs (5 x ZF7363) automatically connected to the new ZD1100 and started upgrading their firmware. Both ZD and all ZFs now run the newest 9.10 build and all the wireless networks work flawless as they did previously. The ZD1100 and the APs are all configured with manually defined IPs in our "client subnet". Gateway is configured in the APs with the same gateway IP as the ZD.
The problem now is that I cannot PING the APs from our "server subnet". I can ping the ZD (located in the "client subnet") just fine from the "server subnet", but the APs doesn't answer as they did before the old ZD1100 was replaced where I could PING all APs and the ZD without any problems. Also as far as I can remember I could also access each AP using HTTP before, this doesn't work either now from the "server subnet" (actually I haven't tested HTTP access to the APs from the Client subnet but I suspect that would work fine). Also I must mention that I have also tested DHCP assigned IPs to the APs but the result is the same, no PING :(
I have tested PING to the "server subnet" from wireless clients and that works just fine.
We use the PING command to monitor the APs from the "server subnet" so I would very much like to have PING access working again. Could anyone please tell me what I need to do to get this working again?
