I have been trying to figure out this for the last two weeks and I am not getting anywhere with it.
Here is the topology I have:
Cisco 3640: (Connected to ISP)
Fa0/0: Connection to Cable Modem
Fa1/0: Connection to LAN (Laptops, Desktops, etc)
Fa2/0: Connection to Cisco 878 Wifi Router (Phone, PS3, Xbox)
Cisco 878 Wifi Router: (Running IOS does not support EIGRP, only RIP)
Fastethernet0: Connected to Cisco 3640, Fa2/0
Fastethernet1/2/3: Not used
-From the Cisco 3640, I can ping to 192.168.10.2 (fastethernet0 on Cisco 87

-From within the CLI of the Cisco 878 I can ping all devices transmitting Radio signals, Phone, PS3, wtc.
-From within the CLI of the Cisco 878 I can ping
Google, fa0/0. fa1/0, fa2/0
-Phone and PS3 connect and authenticate with the Radio interfaces, and show up in the ARP table.
When I browse to 8.8.8.8 on my phone, or even
Google, it returns nothing. When I do a connection test on the PS3, DHCP issues the PS3 an IP, but fails the Internet Check. I am not sure if I have my ACL's and NAT working correctly or if it is something else. About 3 weeks ago, I had the PS3 hard cables to the Cisco 3640 router and the PS3 worked fine. Thank you for your help!
