ICF features

Top Bottom

Do not enable ICF on machines that connect to the internet via another machines connection. NAT devices provide a public address to the internet, and assign private addresses to hosts on your network. Do not use ICF behind NAT device: if gateway does not use NAT, then use ICF. ICF blocks inbound traffic that is not recognised as a response to outbound communication (keeps a table of all outbound requests). Dropped packets can be logged. ICF should not be used on VPN connections. Using Outlook with Exchange will not work with ICF: the exchange server polls the client to deliver mail. ICF will block the exchange server polling because it is not initiated by the client. However, ICF is not enabled by default on internal network cards. Enable ICF using the advanced tab of the network connection. ICF logs dropped packets using W3C format. Enable ports using the settings tab. Services that are preconfigured for enabling are:

Use Advanced to enable other ports, but ICMP is enabled on a tab of it's own. If using ICS with ICF, you can open the port for another IP address using the 'Service Settings' button
