Good Morning,

My name is Khalil and I have problem of connectivity between ISP DSL router to cisco router 2800 and Switches.

My senario is :

1: I have 4 switchs connected by trunk and working fine, communicate each other.

2: I have 2 routers connected by serial cable and using calss 3 ip addessed R1 ip add : 12.0.0.1 and R2 ip add : 12.0.0.2

3: My natwork Ip add : 192.168.128.0

4: ISP DSL router Ip add  : 192.168.10.254

5: Switch to Router there is no trunk and R1 IP add : 192.168.128.250

6: R2 F0/0 IP add 192.168.10.253 (to match IP address of ISP DSL )

7: All my network (Local  192.168.128.0 and 12.0.0.0) using eigrp (can be change after your advice) protocol.

8: ISP DSL configured RIP and I also configured R2 F0/0 port as RIP

9: Redistribution from RIP to Eigrp and Eigrp to RIP done.

But I am not getting internet on my network.  Please I need help to resolve this problem.  Please also If possible write the commands so I will see where I have mistake.  I really thank full to us. 

Best Regards,

Khalil Bhutta

    Please confirm if the ISP router is doing NAT for your internal network addresses to the Internet ?Can you PING an address on the internet from the router that connects to the ISP router ?If this works, but you can not do this from the other routers then you probably need to configure NAT on the router that connects to the ISP router. This my be a good idea anyway.If this doesn't work, have you configured a default route to the ISP router, and are you redistributing this in the routing protocols ?
