Ping between 2 SSID

[Ed Lo]

Hi,

I have 2 SSID broadcasting from the same radio and want to ping between them. They each have their own VLAN and DHCP pool but, I cannot ping between devices connected on each. Is there someting more I need to do in order to do this?

I'm using a 1941w router

thank you

Hello

Do you have:
-any software firewall enabed on the clietns to negate echo-reply?
-any routed acl appled on the l3 interface for these to vlans.
- Can they ping when connected to a wired connection?
-Do these SSID's have layer 7 p2p fw blocking appied on their WLC ( if the AP's are running as LAP)

I haven't configured any firewall unless it's setup by default, no acl has been applied, I haven't tried a wired connected but I would prefer this to work wirelessly, I don't know what the last one is so I'm going to assume no.

Hello
Clients pcs ( microsoft) have software fw's and by default disable icmp messages, so it may be possible that why you cannot ping each other.

If you can ping between each client via a wired connection then this will confirm two things.
1) no software firewall is prohibiting icmp
2) no access-list on the l3 interfaces of these vlans isnt doing the same

Lastly a fw rule can be applied on a WLC where the access points connect to not allow point to point communication (p2P) for certain applications which in some case can negate communication between clients.
