other firewalls (not ipfw)
Authored by: hayne on Jul 10, '02 01:16:39PM

I believe that 'ipfw' itself is merely an interface to the code that actually does the work - which is in the kernel. So, unless these other firewall utilities (that say they don't use 'ipfw') introduce their own kernel extension, the protection you get would be the same and would stand or fall with all others in the (extremely unlikely) event that the kernel firewall code was compromised. And if these other firewall utilities do introduce their own kernel extensions, that would be a cause for concern in itself as such code would likely be far less reliable than the standard kernel code.

Thanks for the clarification. With that, I should say that NetBarrier is its own firewall code, independent of the OS X firewall code.
