Firewall Blocking Traffic between the LAN interfaces
-
windows 7 machines by default firewall would block ping from network that is not local.
On a side note - pointing to anything other then your local dns, even 2nd or 3rd dns is going to bring you problems in resolving local stuff. Since googledns sure and the hell does not know anything about your local network.. And you can never be sure what dns a windows machine will use or latch on too. Also if your windows machines are part of a AD, then they really should only point to your AD dns..
Seems like whoever setup this network before you, left you a real mess ;)

phew…. i disabled the firewall and i was able to ping. Looks like those dd-wrt devices won't be reachable via lan as they don't have a gateway. Thanks a ton mate for helping on this.

No problem.. pretty sure if your running dd-wrt on those APs you would be able to set a gateway. Or you could always nat to get to them from your other network.
Have not used dd-wrt in quite some time… But like 99% sure they supported putting a gateway on the lan interface..
edit: Yup found an emulator so could see the screens, yup they can set a gateway
Also still confused on your whole fowan (dual wan setup) but with the rules on your guest wlan not pointing to to your failover group, not sure what would happen if your default wan went down for their internet access
