Conflict with hardware wireless firewall and Norton Internet Security?

I have been using Norton Internet Security as my firewall for a while
now, and have just installed a wireless router (Microsoft MN-500) on
my PC. Microsoft documentation says that the software firewall
(Norton) is not needed anymore and might cause conflicts. Since the
software firewall provides more protection (such as stopping apps on
my PC from accessing the internet, etc), I would like to keep using
it. Can anyone give me more info on whether there will be any
conflicts or issues with using both the hardware firewall and the
software firewall? Should I just turn off the firewall on my router?

Thanks for your help

Aaron,

I just did the same thing using a Belkin router. I've left NIS
running on all my machines. The trick is that you have to
re-configure NIS to see your new NIC cards. Otherwise, nothing
changes and if a program tries to send personal information out,
you'll see it.

When the cheap NAT router has a FW and I use Linksys myself, do let me
know.

The NAT router meets the specifications in the link and it doesn't have a
FW. If you're lucky, it may have SPI and some FW *like* features and that's
about it, but it doesn't have a FW -- none of them.

A FW appliance will meet the specs in the link and they start out around
$300 minimum.

I run with a host based FW on the machines to supplement the NAT router.

That's not true. A router firewall will protect you from the internet, but
anyone who connects to your wireless LAN is on _your_ side of the firewall.
The router might provide some subset of a firewall, or it might just
provide NAT. NAT will protect you from most attacks from the internet.

It protects you from other devices on your LAN. It protects your wireless
laptop if you connect in some public place. And as you note, it protects
you from some trojan connecting out from your system if it does get in.

I have run both Norton Personal Firewall and ZoneLabs Integrtity as the
software firewall on my laptop. As you probably already know, it keeps you
from doing some sharing that you want to do, from time to time, but I
haven't seen any conflict with the hardware routers that I use. SMC,
Linksys, DLink, no Microsoft.

> software firewall? Should I just turn off the firewall on my router?

No need for that. You still gain protection from NAT.
