| 170703 | 2003-08-29 10:03:00 | Can someone correct me if I am wrong here but I don't think Zonealarm blocks ports - just applications. Zonealarm and the such like are application firewalls - you need a TCP/IP filtering firewall (more commonly run in UNIX or Linux) to block ports. An application firewall acts at the application layer of the 7 layer networking OSI model. TCP/IP filters act at the network layer (layer 3) of the OSI model (see ttp://www2.rad.com/networks/1994/osi/layers.htm or similar). Have a look at www.agnitum.com though - this looks like a TCP/IP filtering firewall for Windows. John |
