I am new to Networking. In our organization we try to setup gateway for security purpose so that we can block certain harmful websites. All I know is gateway is a device. What we have is the LAN setup, Mikrotik router (to assign static IP for every computer in our company).
The details I know is default Gateway, subnetmask and assigned IP address for our company.
I want to know how can I achieve these requirement with gateway. we ready to have a CPU for this process with UNIX/LINUX OS. I guess I can access the gateway from this installed OS, but I don't know how to do this?
Simply, my requirement is achieve security in gateway level, what else I can do with gateway and how to use it.
I hope I can able describe what I want, please let me know If you guys don't understand.
