You have not made it clear if you understand what a firewall is (hardware or software) or if you want to know only about a hardware firewall and how it may differ from a software firewall.

There is a good overview of firewalls here

evaluateit.co.uk/sma…tml

Even if your router does have a hardware firewall built in that is not enough and you should still have a software firewall on each PC.

I use Zone Alarm which is free for home use. Download from here (on the right of the web page)

Overview of the router here

voyager.bt.com/voi…htm

The page above says:

"Full router functions such as DHCP, NAT, PPPoA/PPPoE and stateful firewall".

Software firewalls have a huge weakness in that they can be disabled, … Software firewalls have a huge weakness in that they can be disabled, flip the switch.. no more firewall. (by this I mean, if you get infected with some virus... chances are it'll start disabling any protection currently running)Same can't be said for hardware.



You mean if you get a router with a firewall you can't turn it off even if you have problems with it?

thanks for the reply's i geuss i didnt really make it clear what i wanted/needed to no, the software firewall i no about (avg etc) but ive been told the hardware firewall is the best way to go and i wanted to no if my router had a firewall built in and if so how i set it up etc or if anyone new of a decent router i could buy

Most routers come with firewalls now a days, would be hard to find one with out one. Try and avoid the BT routers they are full of un patched easy to exploit vulnerablitys.

AVG is best known for its anti virus NOT its firewall.

If you have the AVG free edition it dos NOT include a firewall.

Their Internet Security Suite does include a firewall but you have to pay for that.
