Need ICS and Firewall help

[Anthony Ewell]

Hi All,

I have an XP Pro computer connected to the Internet
on its USB Port. And a local area Ethernet network that
connects to the Internet through ICS on the XP Pro computer.

Works well, unless I install a third party firewall on
the XP Pro computer. Then only the XP computer can access
the Internet. (I have tried Zone Alarm and Kerio.)

Question: is there a third party firewall that will
work with this set up? (Forward packets through ICS?)
Am I missing a setting on Zone Alarm and/or Kerio?
(I am aware of M$'s built in firewall, but would rather more
protection.)

Many thanks,
--Tony

If all you want is protection against undesired incoming traffic, M$'s
firewall is fine. If you also want protection against undesired
outgoing traffic, then use Zone Alarm, Kerio, etc.

To use the free version of ZoneAlarm on an ICS host computer, set the
Internet Zone Security to Med. and set the Trusted Zone Security to
Low.

Did that. Kerio will only let ICMP (ping) through. Zone Alarm will
not let anything through. :-( :-( :-( (Disable the firewall,
and away it flies!) Do I need the "Pay" version of these two by chance?

With ZA free, did you install the other LAN PC's in the Advanced or Zone
page on the Firewall setup?

You have to install the Network name and IP address for each PC.
