Cisco 1941 Router Configuration/setup

Hello,

I am new to Cisco routers, and trying to figure out what is needed to complete my router setup.

Currently, I have a Cisco 1941 router, with a VWIC3-2MFT-T1/E1 card installed in EHWIC 0 slot. I have two T1 lines connected to it. I have an ethernet cable coming from the IE0/0 port going to a small 6 port switch which my servers are ran off of.

Now what I am wanting to do, is switch to one cable line, and later add in a second one. I know ultimately the router will have to be configured to DHCP as per the ISP's instructions. I know that the multilink on the router is set to TFTP (if this makes a difference). When i remove the T1 lines, and insert the cable line, the modem and router will not communicate.

I have been searching for days on where/what to start with. Please help.

Thanks,

Cameron

(here is the data that i pulled from rebooting the router. I do not have the log in name and need to reset the credentials soon)

Re: Cisco 1941 Router Configuration/setup

Your router has some configuration on it already and it would help us give you better advice if we knew what is already in the configuration. So would you post the output of show running-config (if there is sensitive information like addresses and passwords you can mask them out.

Changing the configuration register was a good start. I have a couple questions/observations that may help you get started. I notice what appears to be the same public IP address on Gig0/0 and on multilink. Did you get that address from your ISP? If so what kind of connection do you have to the ISP?

In your description you tell us that Gig0/0 is connected to a small switch, which I assume is for the LAN of your network. But that also is the interface where the public address is configured. So I am confused whether this interface is for LAN or for connecting to the ISP. Can you clarify this?
