Hello,

I am having some serious issues with a router configuration on a 1841.
We have 2 routers from our ISP.
The first one is providing a T1 connection
The second one is providing a connection to a frame relay network
All the encapsulation is done on the ISP's routers.
All users connect to the ethernet interface 0/1 of the cisco router.
Then there traffic should be routet to the Frame, if they are accessing resources in a secondary location, or should be routet to the T1 router for Internet traffic.
The 1841 has two build in ethernet ports, and we purchased a HWIC - 4ESW
(4 port Ethernet switch)
eth port 0/0 is connected to the frame relay router 192.168.1.254
eth port 0/1 is connected to the local network 192.168.3.1
port for on the HWIC is connected to the T1 router  ***.***.***.209

int FastEthernet0/0  192.168.1.1
int FastEthernet0/1 192.168.3.1
int FastEthernet0/1/3  ***.***.***.210

I have configured static routes that look something like this.
ip route 192.168.3.0  255.255.255.0 192.168.1.254
ip route 192.168.3.0  255.255.255.248   ***.***.***.209 (T1 connection)
ip route  ***.***.***.0  255.255.255.248 ***.***.***.209

all interfaces are up

I can ping the 192.168.1.254 ip address which is the address of the router which handels the frame relay connection. I can also ping the router at the other end of the frame relay 192.168.2.1

I can ping the Interface of the router which handels the T1 ***.***.***.209
but I can not ping any IP address on the internet.
DNS has been setup as well.

I have dhcp configured for the 192.168.3.0 network.
My workstations receive a ip address in that range via dhcp, and can ping the interface 192.168.3.1
but can not ping the T1 router or the frame router.

Any help would be really really appreciated.
A sample would be great too.

Thanks alot

Drew

Assuming 1841 is the third router; the other two are from ISP

                       INTERNET ROUTER-->INTERNET
LAN--> 1841 <
                       FRAME-RELAY ROUTER--> OTHER LOCATION
Can you post output from the following;

show ip int br
show ip route

I apologize for the late response.
I figured out the problem, NAT was not configured for the LAN interface.
After configuring NAT it worked fine.

Thank you for your replies.
