Cannot access yahoo mail and messenger from client computers (only can connect from server)?

Hi all, I am using cable modem connected through USB to the server, and the server is connected through hub to the 5 other client computers. I can access mail and messenger from the server, but not from the client (other website n yahoo services can be accessed from the client). but only the server that can connect to yahoo mail and messenger.

I am using winroute as a router (with DHCP server) and zonealarm as a firewall.

Can you tell me what might have caused the problems ?

Thank you

Rio

Despite its claims, Zone Alarm does not work well on networks. I often have to disable Zone Alarm just to get internet access.
