3. Select the Block tab or the Pass tab to define your filtering.
• The Block function filters by blocking packets from going out the WAN port
or coming in through the LAN port. To enable the Block IP filter function,
select Enable Block IP Filter Function.
• The Pass function filters by defining which packets can go into your WAN port
or come on to your LAN. To enable the Pass IP filter function, click the Pass
tab and select Enable Pass IP Filter Function.
4. To filter packets to be passed or blocked, use the Packets Defined By list to
select TCP/IP or User.
Packets Defined by TCP/IP:
If you choose to define by TCP/IP, you must enter the packet IP information.
IP Address:
Enter the IP address of the packet to be Blocked or allowed to Pass.
Netmask:
Enter the subnet mask for the packet.
TCP/IP Service Port:
Enter the Socket Port you would like to block or allow to pass (for example,
HTTP= 80)
Privilege Level
Use the Privilege list box to select an appropriate level for this filter.
It is common to set many filter rules for a particular client. At times, the rules you
have set may conflict with one another. When a conflict occurs, the filter with the
higher privilege level will override the other filter(s).
Level one is the highest level, level sixteen is the lowest privilege level.
For example, let's say you configure a filter rule for IP address 192.168.100.72 with
a privilege level of 16 to Pass using socket number 80. At the same time, you set the
same filter rule to block IP Address 192.168.100.72 with a privilege level of one.
The Router will implement the filter to block the IP address 192.168.100.72
because the privilege level is higher.
