10000000

(Logical AND result)

 

 

 

This incoming IP packet (10000000) has a source IP address that does not match the network address in the Source IP Address field (00000000) in the Netopia D-Series. This rule will forward this packet because the packet does not match.

(Perform the logical AND)

 

 

 

 

 

 

 

 

10110000

(Logical AND result)

 

 

 

 

 

 

 

 

Since the Source IP Network Address in the Netopia D-Series’s filter rule is 01100000 (=96 decimal), and the source IP address after the logical AND is 1011000, this rule does not match and this packet will be passed.
