Can anyone tell me how I should set Windows 7 Firewall for HQ Server PC? When firewall is off, it connects to stores (over VPN). I did click on for HQ Server and Manager in the firewall settings.
I read on a newsgroup that "Opening 1433 port is unnecessary and it is dangerous. You have to configure the Windows Firewall Advanced Configuration and enable Incoming and Outgoing settings for ICMP, Network Discovery and File and Printing Sharing for Private networks. Make sure they all communicate to all IP address in stead of just subnets."
Is this right? I don't want to open unnecessary hales.
