Dexlan IP-KVM Manual De Usuario

Single port KVM over IP switch 

 Default policy  

 

This option controls what to do with arriving IP packets that do not match any of the 
configured rules. They can be accepted or dropped.

 

If you set this to “ DROP ” and you have no “ ACCEPT ” rules configured, the 
access to the web front-end over LAN is actually impossible! To enable access 
again you can change the security settings via modem or by temporarily disabling 
IP access control with the initial configuration procedure (see Table 4-1 ) 

 

 

 Rule Number  

   This should contain the number of a rule for which the following commands will apply. In 

case of appending a new rule, this field will be ignored. 

 IP/Mask  

   Specifies the IP address or IP address range for which the rule applies. 

Examples (the number concatenated to an IP address with a “ / ” is the number of valid 
bits that will be used of the given IP address): 

  192.168.1.22/32 matches the IP Address 192.168.1.22 

 192.168.1.0/24 matches all IP packets with source addresses from 192.168.1.0 to 
192.168.1.255 

  0.0.0.0/0 matches any IP packet 

 Policy  

   The policy determines what to do with matching packets. They can be either accepted or 

dropped.

 

The order of the rules is important. The rules are checked in ascending order until 
a rule matches. All the rules below the matching one will be ignored. The default 
policy applies if no match has been found.
