Hi. I am in the process of installing Trend Micro Client Server Messaging Security for SMB on my SBS 2003 Standard Edition R2. It's a little more complicated than I thought, so I am reading the 332 page manual carefully. I am a bit confused when it comes to the firewall part.
As you know, the CSMS for SMB comes with its own firewall, Personal Firewall. The manual recommends disabling the firewalls which come with Windows or disabling Personal Firewall and opening the correct ports and exceptions in Windows' firewalls. From what I can gather, the Personal Firewall seems more robust. Of course, I know these are all software firewalls. I have a hardware firewall in place.
My question is the manual made reference to the SBS Internet Connection Firewall, which is enabled. But, when I looked in group policy, it showed that firewall as well as the SBS Windows Firewall (Server). There is also the Windows Firewall which is located on each client machine. So, do I disale all of them. Or just the Internet Connection Firewall?
