3.6 Security
Port Filtering allows you to enable or disable TCP ports and UDP ports on computers or network devices. Port Filtering
insulates your local computers form many TCP/IP security attacks, including internal attacks by malicious users.
IP Filtering is used to block internet or network access to specific IP addresses on your local network. The restricted user
may still be able to login to the network but will not be able to access the internet. To begin blocking access to an IP
address, enable IP Filtering and enter the IP address of the user you wish to block.
