yeah that is what i was assuming. You will run a cable (rj-45) from the cable modem to the fe port.<br />
<br />
donjohnson is right you will not be able to connect the modems rj-45 port to a t1 port but you should have no problems running it to a fe port.

Have a Cisco 2811, T1 DSU/CSU interface. &nbsp;This is a newb question. &nbsp;I have a modem at home that gives off a public ip of (ie... 66.102.1.99). &nbsp;I only have this one public ip address. &nbsp;<br />
<br />
For mere testing purposes, I was hoping to hook up my Comcast cable modem to the T1 DSU/CSU interface (with RJ-45 cable). &nbsp;Then on FE 0/0 configure a DHCP network. &nbsp;Will this work? &nbsp;Can this be done. &nbsp;If so how would you configure this on the command line. &nbsp;

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
