Hello All, this might come across as a odd scenario and to save posting miles of text ill just explain the technical difficulty that were experiencing in the hope that someone can offer some help:<br />
<br />
We have a Cisco 2811 router with an outside interface address of 192.168.10.1 /24 and an inside interface address of 192.168.20.1 /24. I want the inside range to appear to anything on the outside of the router as 172.16.10.0.<br />
&nbsp;<br />
A basic static NAT will not do the trick because it will translate into a 192.168.20.x address. Ive experimented with bouncing&nbsp;the process off a Loopback interface inside the router so the packets pick up a 172.16.10.x translation but that didnt work because i assume the packets exit interface was not the Loopback address. <br />
<br />
Could Policy Based Routing be the answer?<br />
<br />
Any help is much appreciated.

Cisco NAT via a Loopback interface. Policy Based Routing?

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.
