I've got a generic home 'network' where my ISP supplied modem acts as router with a software firewall built-in. My PCs connect directly to this router to access the Internet.
I want to place a box in between my home computers and the broadband modem. This would act as proxy passing all traffic back and forth, together with a firewall and intrusion detection system/packet sniffer.
- Is there a prebuilt Linux flavour that would do this out of the box so to speak?
- What software on top of the OS is required?
- Would installing a software packet sniffer here be a big performance hit? Would the proxy be a big performance hit? E.g. with multiple boxes active simultaneously, would the proxy need to be multi-core?
- Can I just use any average desktop PC for hardware just so long as there's two network adapters or are there any specific specs for this task?
- Also what is a known working linux/wireless card combo when the wifi adapter is operating in master mode i.e. a WiFi hotspot?
