SIP User's Manual 11. Security
Parameter Description
Source Port
[AccessList_Source_Port]
Defines the source UDP/TCP ports (on the remote host)
from where packets are sent to the device.
The valid range is 0 to 65535.
Note: When set to 0, this field is ignored and any source
port matches the rule.
Prefix Length
[AccessList_PrefixLen]
Defines the 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’.
Source Port
[AccessList_Source_Port]
Defines the source UDP or TCP ports (on the remote host)
from where packets are sent to the device.
The valid range is 0 to 65535.
Note: When set to 0, this field is ignored and any port
matches the rule.
Local Port Range
[AccessList_Start_Port]
[AccessList_End_Port]
Defines the destination UDP/TCP ports (on this device) to
where 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.
Protocol
[AccessList_Protocol]
Defines 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.
Use Specific Interface
[AccessList_Use_Specific_Interface]
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.
Interface Name
[AccessList_Interface_ID]
Defines 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 102).
