Simple Cisco 2621 config?

[barmy]

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.
