Ok for a while I assumed hardware and software firewalls did pretty much the same thing, well the hardware firewall would be better as it was connected to everything. Anyway someone told me the other day that they both do differently things. Currently I run a hardware firewall which is built into the router but no software one.But as it's a network and no machines connect to the net themselves the built in firewalls on mac as well as PC won't enabled as the firewalls seems to be part of the dial up connection. Anyway is there a way of enabling them, is there much point, any alternatives? For PC I know I can just use zone alarm, but not sure for mac as security isn't something I think much about with mac (baring common sense stuff ).
