How to block a chunk of IPs?

Can someone please tell me how to block a whole bunch of IP from a
certain ISP?

If I were to block a range of IP, from aaa.bbb.ccc.000 to aaa.bbb.ccc.
255 --- How would I do that?

I have heard about "HOSTS file" but I do not know how to block a whole
range of IP using that "HOSTS file" thing.

Can anyone please help?

Thank you !

OS: Win 7 Home Basic

In your router you can do it.

The Sygate firewall does that also, which is why I am still using it.
However Norton bought and killed it, so you can't get the professional
version any more. You can still find the free version, but it only
allows 10 rules. Rules can be complex, so you can include several
ranges and/or individual ip addresses in one rule.

Are you talking about Sygate personal firewall pro?
The net is full of sources for that.

you have some nice links???

http://www.oldversion.com/Sygate-Personal-Firewall.html

But isn't it recommended not to use that firewall because it has a
security exploit? I seem to remember reading that and is why I stopped
using it long ago.

Don't know, I don't keep up with stuff I don't use,
hard enough to follow the sploits for what's currently onboard.

Just a note: I believe the oldversions.com link posted is not for the
pro version, just the free version.

Never heard anything about such a problem. The real problem was that
Norton bought it to kill it. Can't have a better product out there as
competition, you know.

nah, some old versions and the pro version isn't free.
Most links are not for the pro version.
Maybe rapidshare.

one security exploit? A few more but it is still the best firewall for
Win98SE. Sygate does work with WinXP. It is a standalone firewall and
not like Norton, Comodo and all the others? part of a complete computer
security system nightmare and you don't have to buy a new PC after an
uninstall. Use a router for internet attacks and iptables for outbound
control.

Nope, I'm fairly certain it did have an exploit in it's last released
version.

I haven't used Win9x in ages and the last time I tried to install it it
was NFG due to not having drivers for newer hardware. I thought iptables
is Linux only? Why use iptables when the Windows firewall is fine and is
only outbound rules anyway unless I go to advanced mode?

you are correct.
I thought that iptables had a Windows clone, but I
couldn't find anything.

how good the Windows firewall is is an item for
comp.security.firewalls.
There has been discussions in the past.

Some problems are:
if you use a local proxy for internet access Sygate's localhost checking is
bad.
Sometimes a blocked IP in Sygates advanced rules isn't always blocked.
Application settings sometimes disappear.

I've been using it exclusively since XP and haven't had any issues yet
so it is good enough for me. I have a router with Linux software on it too.
