Solved Question: Is software Firewall needed for AT&T wifi device?

Specs: Windows 7 Professional, 3.0GHz Quad/8GB
Hello all. For years I've used a router for my wireless networking. Since I live miles from town for the last 10 years, I've had satellite and then later, microwave internet service. Lately I've been trying to streamline my tech services by moving as many services as possible to a single provider. I've been using a wifi device from my cell provider for internet, which has worked quite well by the way.

My question is, I've never used a software firewall when I used a router, but do I need one now? A password is still needed to connect to the wifi device, but I'm not sure whether or not I need a firewall now.

Thanks for your help.

You just cannot have two software firewalls and I imagine that two hardware firewalls in tandem would also pose a problem as well but a software firewall behind a hardware firewall works perfectly.

You have to be a little bit crazy to keep you from going insane.

If your router has a firewall built into it (most likely it does) then a software firewall isn't necessary unless required by whatever software you're installing/running.

A software firewall will tell you if you have rouge outbound traffic like when you have hacker software calling home. A hardware firewall won't tell you that.

Answers are only as good as the information you provide.

Windows has a built in software firewall and it works in conjunction with a hardware firewall. It is certainly safer to have both but I would not use an aftermarket one on recent versions of Windows (W7 or later, even XP had a decent built in one). I cannot see any reason to turn it off.

OK, thanks all for your answers. I have been under the impression for years that it was not good to use two firewalls, such as Windows firewall and a router. I've never fully understood how a router functions as a firewall, but I have always kept Windows firewall turned off. I guess I will turn it on now and see how that goes.

Thank you all again.

It doesn't pose a problem so much as it means (potentially) having to configure things twice.

My internet connects to a SOHO router. That in turn connects to my UNIX firewall running pf. That in turn connects to my switch and the rest of my LAN. If I need to do a port forward, then I have to configure it on both firewalls. Excluding of course my ssh port forward which was only configured on the SOHO router and points to my BSD box.

But other than port forwards, I don't make many changes on the SOHO router. I do all my other filtering just on the BSD box instead. Even if someone were able to hack my SOHO router, the only place they could go would be my BSD firewall.

It's a little bulky, but it is added security and pf gives me much more granular control than a SOHO router does. I don't much bother with the software firewalls on my LAN PC's at all.

Thanks. I have turned the Windows firewall in. I wouldn't consider a third party firewall, although I do use Avast for virus protection. I have used it for years and consider it to be a very good program.

Thank you all again.
