Hi there, Zonealarm is stopping my wireless network ICS and file sharing! Zone alarm appears to be configured to allow the wireless 902.11g wifi card to connect the networked computers to the Internet - but might need clarification on this. The network shows as having 'no connectivity' when Zone Alarm is on in the system tray, and turning Zone Alarm off then connects the network to the other PC and the ICS and file sharing is then possible. Even when Zone Alarm is on in the system tray, the wireless card on the secondary PC still sees the network, but will not allow ICS or file sharing. If I stop Zone Alarm from running the the STARTUP and SERVICES in MSCONFIG, the network doesn't work either. It appears from my fiddling that Zone Alarm has to be in the system tray and running, THEN disabled/shut down in order for my ICS and File Sharing to work. Can anyone figure out why? Any help is greatly appreciated. Thanks Alex

Client to server Communication: * This is done via port 5190 TCP to login.icq.com (please note- allow a bi-directional connection to the port for login.icq.com and not any specific IP address, since it stands for more than one IP address). Client to client communication: * Client to client connection is done using the TCP protocol, using port range 1024-65535. This means that the client needs an open listening port within the mentioned range-- 1024-65535. Found this for you, should allow you to config your firewall for ICQ. Have a look at this site: http://www.duxcw.com/faq/ics/ics_icq.htm as well. Cheers.

I had the same problem with a wired network, and I found two problems in ZA that you should checkfor: 1. In the "Program Control" panel, make sure the TCP/IP command is allowed (green check marks) as a SERVER. 2. In the "Firewall" panel, your ethernet adapter should be listed there. Under the "Zone" column, make sure it says "Trusted." If it says "Internet" in that column, left-click on the word "Internet" and you'll get an option to switch to trusted. Hope this helps. It sure did in my case.
