Hi.
Someone 'here' (somewhere on 'Discussions', can't remember where) mentioned that there is no need to have a router firewall & the Apple FW on together. Why is that? Does the router FW just make the Apple FW redundant or do they clash with each other? Is there any advantage to turning off the Apple FW given that the router firewall is on 24/7?

Sorry, lots of questions...

Thanks in advance.

    Nobody can tell you if you need both... it all depends on your needs, risk tolerance, value of data, what services you have enabled, and also the setup of your LAN.

    You can run both a router/firewall and your computer's firewall- and it's not a bad idea to do this. There are no issues with them clashing.

    Here's one reason you may also want to run the software firewall
    - If a computer on your LAN is compromised, this comprimised system is behind your router/firewall and could carry out automated attacks on your lan or even be manually controlled by another person. The only thing standing between the compromised computer and your computer is the software firewall.

    Thanks for that Jeff.
    No sophisticated LAN here, just my iBook wifi to Belkin router and iMac wardwired to same, to DSL. No services enabled except file and printer sharing on the iMac. Nobody within poaching distance of our wifi so I doubt either machine could be compromised. I'm keeping both SW FWs on for now anyway...

    If you have a laptop and you take the laptop to public WAPs, I highly recommend you leave the firewall enabled because more than likely, you'll forget to enable it at your local coffee shop!
