&quot;I was think I would just search and replace the running-config for 10.20 and replace with 10.76 then TFTP it to the ASA?&quot;<br />
<br />
That's my suggestion. &nbsp;One caveat, the config files on the device itself are saved in a Unix file format. &nbsp;(The file contains carriage returns, but no line feeds, or something.)<br />
<br />
TFTP the config to your PC, edit it with a Unix-compatible text editor like PFE32, then TFTP it back.<br />

Hi<br />
<br />
I have a Cisco 5510 which has four interfaces.<br />
<br />
One of the interfaces named LAN has the subnet 10.20.0.0/16. A number of firewall rules and objects are configured with this network range.<br />
<br />
I need to change the subnet from 10.20.0.0/16 to 10.76.0.0/16.<br />
<br />
I was think I would just search and replace the running-config for 10.20 and replace with 10.76 then TFTP it to the ASA?<br />
<br />
Is the easiest way?<br />

ASA5510 Advice - on how best to change IP address on i/face and all rules, objects

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.

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.

Network Operations

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
