One of my clients is changing ISPs therefore they will be obtaining a new public IP address. &nbsp;I have all the new information...IP, SM, Gateway and DNS. &nbsp;THe problem is, that I am not familiar with how to program Cisco Routers. &nbsp;I assume I will need to change the IP address of the router itself and the public IP address? &nbsp;Can somebody walk me through this process. &nbsp;Just to give you a little more info on the environment; The T1 currently comes into the Cisco 1700, then a crossover to a Sonicwall Firewall, then a cable from there to the switch. &nbsp;Please advise.<br />

How to change IP address on Cisco 1700 Router

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.
