Zone Alarm firewall

[LarryH]

Hi I have installed Zone Alarm's firewall. Do I have to turn off MS's
firewall?
Thanks Larry

You don't have to, but you should. It does nothing that ZA
doesn't do, so it provides no extra protection. Having two
firewalls running will also slow you down (at least slightly) and
presents a risk of their interfering with each other.

 

[Ken Bessler]

Yes

Can you elaborate? I run ZA Pro *and* ICF and I'm not seeing
any problems - I'm also running a Linksys hardware router/firewall.

Do I need to make changes to ICF or the Linksys? Why? Details?

If your router does NAT, you do not need ICF. ICF protects against
incoming tfc only, so it is not very good. ZAPro protects against incoming
AND outgoing tfc, and if a trojan, worm, or spyware payload activates, you
will be protected by ZA from it calling home. You should not run ICF with
any other firewall...ZAPro is a far better choice than the lowly ICF. If
your router is properly configured, it will protect you against incoming
tfc, thereby making ICF redundant. You need ZA Pro to protect against
outgoing tfc.

Ok, I'll turn off ICF. But what is NAT? How do I tell if my router, a
Linksys BEFSR41, is running NAT?

Signed, confused......

No. When I install XP Pro then Zone Alarm, the XP Pro firewall is disabled by
the ZA installation.

 

[NobodyMan]

Yes

Incorrect; the correct answer is "no." They coexist just fine - even
though you don't need to run both.

 

[NobodyMan]

No. When I install XP Pro then Zone Alarm, the XP Pro firewall is disabled by
the ZA installation.

I had a different experience. Every version of ZA I've ever installed
left the XP built-in firewall in an active state.

Greetings --

You don't _have_ to, but it would be a good idea.

Running two software firewalls simultaneously is unnecessary and
can cause conflicts, possibly negating the protection of both. In any
event, having two firewalls running simultaneously is an unnecessary
drain on system resources.

I have ZA running. How do I find out if my XP Home ICF is also running and
if it is, how do I disable it?

I have ZA running. How do I find out if my XP Home ICF is also
running and if it is, how do I disable it?

1) "Start|Connect To|Show all connections...", then right-click on your
connection.
(or right-click on the connection icon in your Notification area)
2) Click on "Properties"
3) Click the "Advanced" tab. If ICF is enabled, there will be a check mark
next to "Protect my computer and network..."

To disable ICF, remove the check mark, then "Ok" out

That router does have NAT, as do almost all SOHO routers. NAT is how
routers are able to share 1 IP address among multiple computers.

I know absolutely nothing about routers. Sorry..

 

[Malke]

I know absolutely nothing about routers. Sorry..

If you are using dhcp with the router, it is using NAT - Network Address
Translation. It's what allows the router to get the outside IP address
from the cable or dsl modem and then "turn around" and assign internal
IP addresses to all the computers on the LAN. To learn more about your
particular router, read the manual that came with it (the manual may be
on the included CD). Linksys also has information on its website:
www.linksys.com.
