RouteFinder RF500S User Guide
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).
Note: Level one is the highest level, level sixteen is the lowest privilege level.
Example:
Let’s say you configure a filter rule for Source 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 RF500S will implement the filter to
block the IP address 192.168.100.72 because the privilege level is higher.
Note: If conflicting rules have the same privilege level, then the RF500S will block the packet.
Click Insert to add each IP address to the list.
To remove a defined packet, select the packet you’d like to delete from the table and click Delete.
Packets defined by User:
If you choose to define by User, you must define the byte pattern of the packet(s). The RF500S
uses the defined byte patterns to block or pass packets from the WAN or from the LAN.
1. In the Block dialog box, select Enable Block User Defined Pattern Function.
2. In the Packets defined by User field, select From LAN or From WAN.
Starting from which byte number:
In this field, indicate the first byte in the packet the RF500S should read to determine if the byte
pattern (in Hex) is one that should be filtered. Exclude the PPP header. Start from byte 0 of the
network protocol.
Byte Pattern (in Hex):
Enter the packet byte pattern that you would like the RF500S to recognize as a packet to be
filtered. (Block/Pass from the WAN to the LAN). The maximum pattern size is 12 bytes.
Click Insert to add each byte pattern to the table.
To delete a defined packet, select the packet in the table and click Delete.
