What is a good firewall for AMD 64 Athlon systems?? I have found several to
not be compatible and reboot the machine on install.
The latest versions of Norton Personal Firewall and Zone Alarm should
function fine in a 32-bit windows environment on an AMD64 system. As
I have no access to the 64-bit versions of windows, I can't say
whether they'll crash or not in that environment or if you'd need to
track down a 64-bit equivalent. If you're running a 32-bit version of
windows, then the issue is likely a problem with some component of the
windows installation or some other misbehaving piece of software.
If you're running an AMD64 version of Linux or even one of the x86-32
versions, you should be able to setup a working firewall using
IP-chains. The software is included with many distributions, and
there are a variety of frontends available if you want the process to
be more automated and easier.
If none of this works, you can always buy yourself a router. A cheap
one runs about $40-50, which is roughly what a windows commercial
firewall program costs. The router's firewall features would allow
you to open and close specific ports to limit traffic, but wouldn't
have the program-specific control that a software firewall would.
As it's a stand-alone hardware device that sits between your net
connection and the computer, it work regardless of what's happening on
the host machine.
