Cicso Router setup

[tysmakitla]

Hi All
I have a cisco 1601 that I want to configure on my Office network. What I want to do is to use the router for the office connecting it to an ADSL router that Is already working. So everyone in the office will connect to Cisco then the Cisco will connect to the ADSL router to give everyone Internet. Can someone please help me with the setup. I don’t know anything about Cisco but I do know Linux very well:cool.

Thanks

Why?

How many ethernet interfaces does it have?

Edit: Just checked and the 1601 only has one ethernet interface so I don't see the point unless you wanna start playing around with sub interfaces and vlans which will probably not work with your existing kit. I don't think it has any adsl wan interfaces available either. You need a router with two ethernet interfaces for what you want to do but I still don't see the point.

I would have rather gone with a switch rather than a router....

How many ethernet ports are availale on your 1600?
What IOS version are you currently running on it? You can get this information by typing the following:

>sh ver

It should give you output on the first line along the lines o this:
Cisco IOS Software, 3600 Software (C3640-JSX-M), Version 12.4(25d), RELEASE SOFTWARE (fc1)

Agreed. I know you get add-in cards that will give you at best another 4 ethernet ports, but your only real option would be with subinterfaces, and that is not eactly point-and-click to set up.

I suggest use a switch for your access layer and connect your router to that.

The Router has 1 Ethernet Port, Version 12.1(25)

I am afraid you won't be able to connect the computers the way you are intending. Your one ethernet port will (likely) be used to connect your two routers together, leaving you with nothing to connect your PC (singular) with. The best bet would be to get a switch (doesn't have to be an expensive one) and connect it to your current ADSL router.

As the 1600 probably doesn't have any Wide-area Interface Cards, you won't be able to connect your DSL line to this router either.

You, my friend, are square out of luck, sorry.

What's your reasons for wanting to do this? If it has one port, you might need to connect both routers to a switch. Then on the 1601 configure an ip route like this:

Conf t
ip route 0.0.0.0 0.0.0.0 192.168.100.1 <~ adsl router Lan IP Address
end
copy run start

This essentially routes all traffic to everywhere to the adsl router which will in turn route traffic to the internet

Although, with an already working router, why add an additional router? Doesn't make sense.

End of the day you have wrong equipment. You need a layer 2 device i.e. switch for what you are trying to do, i.e. connect to an existing router, or a layer 3 switch, to provide you with some form routing.

A 1601 simply won't work, and if you manage to get it working, it is by far not going to be the most efficient way of doing it.

I have to agree with you. Its not the most efficient way of doing it.
