IP access control parameters
Parameter Description
Enable Firewall Enables access control based on IP source addresses.
Default Policy This option controls arriving IP packets that don’t match any of the
configured rules. They can be accepted or dropped.
Note: If you set this to DROP and you have no ACCEPT rules configured, access
to the Web over LAN is disabled. To enable access again, you can change the
security settings via modem or ISDN dial-in or by temporarily disabling IP
access control with the initial configuration procedure.
Rule Number This should contain the number of a rule for which the following commands
will apply. This field will be ignored, in case of appending a new rule.
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 or 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
