integer ::= 0–9[0–9…]

net_address ::= {hex_digit}

Examples

Example 1: Filters all SNMP traffic between a manager and an agent. The manager

address is 200.200.150.120 and the agent address is 200.200.150.110. There are two

patterns used in the pattern list, the first one for the packets from the manager to the

agent, and the second one for the packets from the agent to the manager. The first

pattern has or as the operation, whereas it is set to none in the second pattern.

Example 2: Filters all Web traffic between a browser and a Web server. The Web

server address is 200.200.150.120 and the browser address is 200.200.150.110. There

are two patterns used in the pattern list, the first one for the packets from the server

to the browser, and the second one for the packets from the browser to the server.

DstAddrResult=200.200.150.120, Protocol=TCP,SrcPort=0,DstPort=80,

Example 3: Forwards only Web traffic on the RAS. There are two patterns, one that

allows Web requests to pass through and the other to allow the responses.

Example 4: Filters Telnet packets on the network. Only one pattern is needed to block

all received packets that have a destination port number of 23.

Telnet_Filter=“Filter all Telnet packets”,IP,input,filter,

Protocol=TCP,DstPort=23:
