Hi,<br />
<br />
In setting up the cisco 1841 router,<br />
<br />
I use the FE0/1 for the Wan for the internet connection<br />
<br />
Than use FE0/0 for the Lan, giving FE0/0 a private ip. And doing nat out through the FE0/1<br />
<br />
My question is, do i need any accesslist anywhere to protect the Lan from outside intruder. or the Nat already protect it? <br />
<br />
thanks<br />

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.
