Hey guys, first of all please excuse my poor english. I am a programmer with little knowledge of computer networking in need of a solution ASAP.
I want to have connections to two networks in one system. one connection for internet and another to an intranet. but there is a security problem. the intranet network has sensitive information on it and only users with specific IP address can use it. people in intranet network believe that having both internet and their intranet connection in one system, exposes the intranet to the hackers. how can i secure the intranet when system is connected to the internet. because of the limited resources i prefer software solutions. please show me the right direction.
thanks a lot
 


This is a very common scenario, just about every company with computers on the planet has this setup, they have an internal network and a connection to the internet. You need to do some reading on how to setup a firewall, a DMZ as already linked if you want to have a server setup that outside people can access, anti-virus tools and have a internet usage policy in place.
