Question

i have just put on a new wireless router in my home. do i really need a firewall established on it? i have a good working antivirus programs on my computers with firewall on each one. DO I NEED A FIREWALL IN THE ROUTER AS WELL? HOW IMPORTANT IS IT?

Answer 1

No, if you have a firewall in your PCs your home router don't need its own firewall. Having your PCs with their individual firewall is the best protection that you can achieve.

Have this three security in place and your computer will be good from here to 2010:
Antivirus
Firewall
Anti-spyware

===========
Omg, this guys below are insane. Firewalls do not protect against viruses. And having a firewall in the router and other in your computer will block you from many things on the internet at one point you wont even be able to surf websites or use messengers.

Answer 2

Well you may not actually need a firewall on the router, but there are some things to be aware of:
1. Your router needs some kind of security to keep others from using it's wireless connection: usually this is a WEP or WPA key so your computer can use the router and others can't.
2. The router may employ a firewall whether you want it to or not. Or contrarily, there may be no way to install a firewall on your router.
3. The router firewall may operate at no significant performance cost to the router, whereas firewall software on the computer always incurs a performance cost to the computer. If you want good security, run both. If you're choosing one or the other, go with the firewall on the router.

Answer 3

Routers are the best firewall walls available even if it doesnt say firewall on the box. Software firewall can be turned off by hacker but hardware firewall (router) cannot.

Answer 4

its highly recommended

most routers have a built in firewall you can access through the routers website. (http://192.168.192.1.1 is default)
also why let the viruses even get into your network
block them before they can reach anything

Answer 5
