Observe the image attached to this post first please. It displays a setup of the network i’m trying to protect from all evil harm that’s possible.
The DSL modem + wireless + firewall is one of those all-in-one solutions including wireless connectivity, dsl modem, wifi access, voip and a built-in firewall. One of those software thingies you can setup via your browser, it’s configured to block the standard things, but not properly fine tuned.
The wireless setup uses WPA TKIP PSK on a fixed channel with a hidden SSID as protection schematic. Perhaps later on i’m going to change this to WEP PSK with hidden SSID to enable old wireless devices on this network, but i’m not convinced i should. At the moment two other devices use the wireless network to connect to the internet 24/7.
Both switchs are simple autosensing 100mbit switches. No extra fancy stuff.
The majority of the devices (more computers and even more computerS) are connected via a UTP LAN to said switches. A simple wired network so to speak.
I was wondering if it would be beneficial to extra harden the security of this network setup with the aid of a hardware firewall. To my best opinion it should then be placed between DSL modem and UTP switch 1. (Number 2).
The problem here is, how to protect the wireless devices as well?
Question: Would a hardware firewall give me any protection enhancement and is there a hardware firewall that can also protect the wirelss devices?
