You can also configure IP filtering on the SBG for secure Internet access. When the IP filter is on, all
incoming traffic from the Internet to your network is blocked by default unless it is initiated from your
network. This means that probes from the outside to your network are not allowed, but you can safely
browse the Internet and download files.
