Help config Cisco 2612 Router for home network

[pieczjp]

I have purchased a used Cisco 2612 router from a grocery store that has closed. Their NOC department have already flashed the bios so I am able to access the unit. I want to use this router for my home network but I do not have any Cisco knowledge. I know how to gain access to the router via "console" cable and using "hyperterm" but that's about it. I followed a few instructions from the internet but those failed to help. When I seat my Category 5 plug (carring the signal from the ISP) into the routers DSU I only get a yellow light. I know that it's suppose to be green. Any help on this is appreciated. Thanks.

Here is some info.
IOS ver = 12.1(4)
IP Address. . . . . . . . . . . . : 172.16.0.17
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 172.16.0.1

some questsions:

1) What kind of broadband or networking services is your ISP providing to you? Cable modem? ADSL?...etc
2) Did the ISP provide you the modem or CSU/DSU device or you got a CSU/DSU module in your router?
3) Did they provide you static IP addresses or you'll be automatically allocated an IP address?
4) Is PPPoE involved?
5) Is this 172.16.0.17 the IP address of your PC?
6) Do you have other PCs/Servers in your network that will host some services like

http://WWW or

FTP for others in the Internet?

I currently reside in a apartment complex that provides TimeWarner RoadRunner Broadband. The signal comes from my Motorola cable modem. From there runs a patch cable to the CSU/DSU on the Cisco Router. Then runs to a Vertical Horizon 24 port fast ethernet switch.

I don't know if it is static or dynamic IP but my last ocipital IP of 17 has remained the same for over a month. The 172.16.0.17 IP is the IP of my Server. The way my network is set up is that I have a file server and two workstations.

well...any numbers or words beside or around the physical "CSU/DSU" port on your router? Something like S0, S0/1, F0, F0/1,...etc.

So how did you connect all your PCs and servers to the broadband service before? Or did you just subscribe the broadband service and didn't use it before?

On the module for the CSU/DSU it has a LED light for the following: TD, RD, LP, AL. Then underneath the RJ-45 (CSU/DSU) jack it says "56/64 DSU/CSU." Then to the right there's another LED light that reads CD. Then farthest to the right it says WIC 1DSU 56k.

Currently the PC's are go from patch cables to the switch then to the modem. The only form of firewall is W2K3 firewall feature but I'm trying to bypass this and use this Cisco Router since I have it.

Then I suppose currently your cable modem is the default gateway of your PCs/Servers which reside in a single flat network 172.16.0.0/24.

If that's the case, I don't understand why you need a CSU/DSU in your router since you already have a cable modem outside.

Btw on the router you should have only 1 token ring and 1 ethernet port, right?

So this router will not work with my connection? Is there a way to make it work? the router does have 1 token ring and 1 ethernet port.

Need two ethernet ports to use it. Can get a NM-1E ethernet module on ebay pretty cheap. That would add the 2nd ethernet port that you need.

Just curious, why do you want to set a router in your flat network? What do you want it to do for you? Access-lists to block traffics? QOS?

I just wanted to learn to configure it. I'm just going to sell it on eBay.
