Hi there,

I'm totally new to IOS though i've read the books for the CCNA exams...

I've been handed a cisco 2621 and asked to make it route between two seperate networks.

The first network uses the range 10.1.x.x 255.255.0.0

The second used 192.168.x.x 255.255.0.0

Basically i need for clients on one network to be able to communicate with each other, and also i need the clients on the second network to be able to route through the first to access the internet. Static routes would be a lot of work to set up so really i'm trying to do dynamic nat.

I guess my first question is can this be done with what i've got? And second, can anyone suggest a config? The ones i've tried havent worked so far....

Many thanks,

Phill H.
 
Yes this can be done.
simple config given limited info.

interface FastEthernet 0/0
description Internet side
ip address 10.1.1.1 255.255.255.0
no shut
interface FastEthernet 0/1
description Client side
ip address 192.168.1.1 255.255.255.0
no shut

ip route 0.0.0.0 0.0.0.0 10.1.1.2 (forwarding router to internet)

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

1)you need to point clients to 192.168.1.1 as default gateway.

2) you need to have the forwarding router (not given) perform NAT for the 192.168.1.0/24 subnet. You must also have a return route in the forwarding router that is attached to the Internet ( ip route 192.168.1.0 255.255.255.0 10.1.1.1)

3) Static routing is simpler. Dynamic depensds on your upstream router. since you only indicate two subnets static will be just fine.

 
Many thanks for your response, thats helped a lot...
