I know this is a stupid question but I have no idea what to do. I have a Cisco 3660 Router and need to know how to set it up. I can telnet into it and get to the initial setup configuration but have no idwa where to go from there as to how to set it up properly. We do connect to the Internet via DSL and our current router handles the username and password for the DSL. Also where do I hook the DSL modem upto the Router and the Router to my Switch?

The router you have is a much larger scale router than what you need. Since you have a DSL connection you will need a DSL router. Check the hardware on your router
from the command prompt
Router>
This is what it will look like if it has no config on it.
Router>en
Router#>sh ver

Capture the output and paste it here so it is easier for a techy person here to help with what you want to do.
 
I know it is bigger than what I need but I have it and want to use it we didn't have to pay for it so I though why just let it sit around and take up space.

Here is the Configuration:

Here is where you may get into trouble with this router.
On the back of it you will see the Console/Aux/Ethernet/Serial ports
Typically the serial ports are on top of the Ethernet/Console/Aux ports
There will be a card, can you tell me what kind of card that is in there?
My guess is it is a T1 DSU/CSU, better known as a WIC.
 
Since it is a T-1 Card you can only use that with a T-1 ckt. If you want to use this as a DSL then you will need that type of card.
 
This router can terminate your DSL line with a WIC-ADSL module. This module can be purchased on eBay. You will also need to upgrade the IOS running on the 3640 to at least 12.3 code with ADSL feature set. Other than that, your router seems to be maxed out on RAM, and would be a great router (definitely overkill, but if you're learning Cisco, why not?).
 
I would recommend selling this on eBay and buying a router that you can use for DSL rather than buy the DSL card and then upgrade your IOS, assuming you have a contract with Cisco and can do that.
 
If you want to do this then i would reccomend going to cisco.com and doing a search on what you are looking for .
 
You've got two etherent ports on that router. Why not just change the DSL router to work in bridge mode only and then configure your Cisco router for pppoe, DHCP, and NAT. No additional hardware needed. I have done this at home with a DSL router in bridge mode and a 1750 router and it worked great.
 
I agree with JOAMON about bridging, that is definitely the cheapest way to utilize this router, not sure if the code that runs on it now supports irb, it should, cause bridging has been around for a long time now, but with a DSL wic you can actually poll the line and get line readings and stats, so it's definitely a cool thing to learn. Again, all depends on your wallet.

I wouldn't sell this router on eBay cause it is modular and can be utilized in various ways, versus a smaller box like the 1750 which is quite limited in it's functionality.
 
If it's going to be that much trouble I will get a different router.

You've got a great router there already...would not be all that much trouble to use it. Just need to configure DSL router for bridging our just get a DSL modem compatible with your type of service. Probably DMT as not to many people use CAP anymore.
