Filter Settings
You can use Filter Settings to choose which packets are allowed to enter the network and which
packets will be blocked. Filter Settings can be used to filter network services such as Mail, WWW,
FTP, Telnet and News.
1. From the main Manager dialog box, select your RF802EW, then Filter Settings.
2. The Filter Settings dialog box displays.
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 and 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 and 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 filters.
