I have assign x.x.x.120 to e0/1 as outside interface. I need to use different pubic IP address for setup Nat for exchange server like x.x.x.121 . I wonder if I need assign this IP address to e0/2 or I just need to add a IP address as a object.<br />
<br />
When I try to assign this IP address to e0/2 , I am getting overlap error.<br />
<br />
Please advise.

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.
