So, should I have the Mac firewall on in addition to the router firewall or is it unnecessary?
It would depend on if there were other Wifi/Airport computers within range, what services you have enabled, and form of encryption you use. The Router's Firewall would protect you on the Internet.
Well, there are several other wifi networks I can detect when, for example, I turn on my iPhone or iPad. They show a little lock icon meaning I can't use them without their pass phrase. I don't see that for my own network but that's because I've previously entered the password into my iPhone and iPad and they remember the pass phrase. I'm pretty sure other people see the lock icon and can't get onto my wifi network. As to the form of encryption I use, that's beyond my ken. All I know is that my wifi network requires a password; authentication is set to WEP-Open and that my wifi system has a name and pass phrase that I gave it at some previous time and that I had to enter those in my iPhone, iPad and now the Epson printer in order to access my wifi network.
As to what services I have enabled, I don't know too much about that as applied to the router's firewall. I don't know that enabling services is something I can do with the router. Maybe it's just that the router doesn't label things "services". I see for example the option to enable "Public Routed Subinterface", or "Public Proxied Subnet (NAT/Routed)". (These are disabled, BTW.) There is also an option to choose either "Maximum protection – Disallow unsolicited inbound traffic" or to "Allow individual application(s)" which is followed by a list of what look like games which can be enabled. I have it set to the former, Maximum protection."
In my Mac's Sharing control panel under the Services tab I have enabled Personal File Sharing, Windows Sharing (I run Windows on my MacBook at times), and Printer Sharing. Under the firewall tab those things are also selected (and grayed out) but I have also enabled Network Time. If I turn off the firewall on my Mac will I lose those services? Will my Mac not know what the correct time is anymore, for example?
Does that tell you enough to be able to say with certainty it's OK to turn off my Mac's software firewall in Prefs?
Thanks so much.
