6.1.3 - Network Connection Settings

-- Internet Connection Sharing (ICS) --

ICS provides Internet access for a home or small office network by using one common connection as the Internet gateway. The ICS host is the only computer that is directly connected to the Internet. Multiple ICS clients simultaneously use the common Internet connection and benefit from Internet services as if the clients were directly connected to the Internet service provider (ISP). Security is enhanced when ICS is enabled because only the ICS host computer is visible to the Internet.

The addresses of ICS clients are hidden rendering them invisible to the Internet.

Is this feature implemented in the NetGear DGN2200 Modem Router,

such that the only way my data files can be accessed from the internet

is if I inadvertantly open an Email or click on a website link

or download a file or program

that results in Malware being loaded on to my Computer ?

How do I verify that this feature is active ?

Thanks for your help.

Hello BrS7

I am not sure if the DGN2200 is able to do this or not still checking but I was able to find a article from microsoft on how to do this on your own network if you are looking to do this.

Thanks for your help Darren
I would still like to know if using a router
does provide some level of invisibility to clients.
I realize that there is no absolute protection.
I do not have a spare computer to dedicate to ICS.
