I have a Cisco 2811 with 2 fastEthernets. This is configured with:
LAN0 (192.168.0.0/24) <---------> f0/0 (192.168.0.6) --- f0/1 (192.168.1.6) <----------> LAN1 (192.168.1.0/24) <----------> INTERNET
The 2811 can access to Internet. I can ping any host (google.com), and 192.168.0.x, and 192.168.1.x. All is OK.
But i can't ping from 192.168.0.x to 192.168.1.x. LAN1 can't access to LAN2.
This is the configuration
Thanks.

is this the entire config?
Im assuming that fa0 and fa1 are going into seperate switches?
there are no acls configured?
which interface is for internet?
whats the reason for the 2 subnets?

Hi, Yasien
Yes, this is te entire config. An this is the graphical configuration:
LAN0 (192.168.0.0/24)
||
f0/0 (192.168.0.6)
||
f0/1 (192.168.1.6)
||
LAN1 (192.168.1.0/24)
||
MODEM/ROUTER (192.168.1.1)
||
INTERNET
I have 2 subnets because the 192.168.1.x is a subnet with cameras, etc. The default gateway of entire network is a modem/router zyxel with IP 192.168.1.1
Both f0/0 and f0/1 are connected into separate switches.
Thanks.

so devices on 0.x can get to the internet ?
devices on 1.x can get to the internet?
03-05-2013 02:04 AM
so devices on 0.x can get to the internet ? => NO INTERNET ACCESS, GATEWAY of devices is 192.168.0.6
devices on 1.x can get to the internet? => YES, because GATEWAY is configured to 192.168.1.1 directly.

try
ip routing
OR
int fa0/1
no ip nat outside
ip nat inside
OR
remove NAT from both interfaces
im guessing your modem is already doing NAT
