I have installed a Netgear WGR614 router that has NAT and SPI enabled. It controls my wired desktop and wireless laptop computers. I am trying to learn a bit about hardware firewalls now and have read messages here that software firewalls are not needed if you have a NAT router.
Other than perhaps wanting to monitor outbound traffic do I need my desktop Sygate 5.6 software firewall anymore?
Should I bother turning on the Windows firewall on my laptop?
Will I continue to be able to use file sharing applications without making specific rules in the router?
How about other applications that use non-standard ports?
Thanks
