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.
Warning
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.
Warning
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.
