Got internet connection sharing working with Free Zone Alarm

[Yitzak]

Symptoms:
Configured host PC to share internet connection. The client pc could
not do a domain name lookup.

I.e on the client
1. ping www.bbc.co.uk would not resolve
2. ping 212.58.224.12 (www.bbc.co.uk's IP address would work)
3. Switch off Zonelarm on the host computer and step 1 would work.

Now I was using Zone Alarm Free version 5.

1. Putting the security level onto medium for the internet made it
work Sometimes!!
2. Using Advanced optins on firewall settings and allowing outgoing
DHCP requests worked again sometimes...

I really got fed up and went back to Zone Alarm 4.5 and it works all
the time now with medium security. Apparently medium shows your PCs
ports wheras High security hides them - both settings block teh ports
thou..

Is the ICS host (192.168.0.1) configured as your Primary DNS server on
the ICS client? Is the ICS host configured as the Default Gateway on
the ICS client?

2. ping 212.58.224.12 (www.bbc.co.uk's IP address would work)
3. Switch off Zonelarm on the host computer and step 1 would work.

From the ICS client?

Now I was using Zone Alarm Free version 5.

I would suggest you get it working with the Internet Zone set on HIGH,
otherwise you are taking more risks than necessary. Again, try the ZA
forums.

Zone alarm and most personal firewalls have a trusted zone. Try adding your whole
subnet to the trusted zone. --- Steve
