zone alarm/network query

Greetings

I have just set up a network between my desktop PC and a laptop but when
Zone Alarm (free version) is running on the PC, I can't "see" the laptop. As
soon as I disable Zone Alarm, there is the laptop and I can move stuff
to-and-fro. Can anyone advise please on whether I can tell Zone Alarm to
accept the signal from the laptop - and if so, how? The laptop is just using
XPs own firewall at present.

I'm using a Linksys modem/router (WAG54G). This is hardwired to an ethernet
card on the PC. The laptop has a Linksys wireless adapter card.

This has been setup to test if the network will work, in readiness for going
broadband (now ordered).

I know the router has built in firewall stuff, but I've seen in newsgroups
that it's advisable to have a software one as well.

All help appreciated.

routers & XP firewall only against protect incoming , i'll spray that
again.......

routers & XP Firewall only protect against incoming attacks, they do not
prevent outgoing 'phone-home' or mailer virus etc.
so run ZA on every machine with access to the outside world via however!.

you might possibly need to add the ip range / ip of the laptop / gateway
into all trusted zones of any ZA you run.

Thanks Mike, I'll try to sort that. Didn't realise routers firewalls had the
same limitation as XP

What you're saying is true but only with the routers default settings. My
Netgear router can be set to block all outgoing ports and then you allow
only the ones you require. I don't know about other makes of router.

You need to identify the laptop as being on the the "trusted network"
any easy way to do this is to remove Zonealarm and replace it with Kerio
Personal Firewall. Kerio is very easy to to set up in this type of
situation -- it tries to idenify the trusted network at installion and
ask you to verify or customize the address ranges it finds. After that
it will initially ask you to confirm as each applcation is run if it is
ok t let contact the outside world and the same for incommimg
connections untill it builds up a set of rules.
The version of Kerio I use is 2.1.4 I fnd this version simpler better
and slimmer than the version 4.x.x Version 2.14 of Kerio can be found
at computercops.biz

While many routers can be configured to control outgoing connections on
a per-port basis, software firewalls can do it on a per-application
basis - this tends to be rather more useful when it comes to stopping
malware from getting out.

That's exactly the way Zonealarm works with the exception that it *does*
identify the Trusted Zone. ;-)

Very true, I know with Kerio a specfic application can be restricted to
a specific port, specific protocol AND a specified internet end point
address. Kerio also runs an MD5 checksum which flags if the
applications exe has changed.
But I like the added protection of a hardware firewall be it on the
ADSL-Router or better still running on a PC running IPCop or similar.

So going back to my original query, why didn't Zone Alarm allow me to
contact my laptop - is it because ZA was already installed before the
network was set up?

yes, often happens, i then to disc the internet then disable ZA, get network
working, re-enable ZA, reconnect internet.
works most times
