Table 3-13: Internal Firewall Parameters

A read-only field indicating whether the rule is active or not.
Note: After device reset, all rules are active.
IP address (or DNS name) or a specific host name of the
source network (i.e., from where the incoming packet is
received).
IP network mask. 32 for a single host, or the appropriate
value for the source IP addresses.

A value of 8 corresponds to IPv4 subnet class A
(network mask of 255.0.0.0).

A value of 16 corresponds to IPv4 subnet class B
(network mask of 255.255.0.0).

A value of 24 corresponds to IPv4 subnet class C
(network mask of 255.255.255.0).
The IP address of the sender of the incoming packet is
trimmed in accordance with the prefix length (in bits) and
then compared to the parameter 'Source IP'.
The destination UDP/TCP ports (on this device) to which
packets are sent.
The valid range is 0 to 65535.
Note: When the protocol type isn't TCP or UDP, the entire
range must be provided.
The protocol type (e.g., UDP, TCP, ICMP, ESP or 'Any'), or
the IANA protocol number (in the range of 0 (Any) to 255).
Note: This field also accepts the abbreviated strings 'SIP'
and 'HTTP'. Specifying these strings implies selection of the
TCP or UDP protocols, and the appropriate port numbers as
defined on the device.
Determines whether you want to apply the rule to a specific
network interface defined in the Multiple Interface table (i.e.,
packets received from that defined in the Source IP field
and received on this network interface):

[0] Disable (default)

[1] Enable
Notes:

If enabled, then in the 'Interface Name' field (described
below), select the interface to which the rule is applied.

If disabled, then the rule applies to all interfaces.
The network interface to which you want to apply the rule.
This is applicable if you enabled the 'Use Specific Interface'
field. The list displays interface names as defined in the
Multiple Interface table (see ''Configuring IP Interface
Settings'' on page 76).
