5.3.2 IP Filtering

Choose Advanced > IP Filtering to display the following page.

Figure 19 IP Filtering configuration

This page allows you to configure the CMRG to prevent local PCs from getting

access to the WAN by specifying those IP addresses that should be filtered.

By entering starting and ending IP address ranges, you can configure which local

PCs are denied access to the WAN. Note that you only need to enter the LSB

(Least-significant byte) of the IP address; the upper bytes of the IP address are set

automatically from the CMRG IP address. To activate the IP address filter, you must

also check the “enable” box and click apply. The enable box allows you to store filter

settings commonly used but not have them active.
