Table 5-34: Internal Firewall Fields
Parameter Description
Is Rule Active
A read-only field that indicates whether the rule is active or not.
Note: After reset all rules are active.
Source IP
[AccessList_Source_IP]
IP address (or DNS name) of source network, or a specific host.
Mask
[AccessList_Net_Mask]
IP network mask. 255.255.255.255 for a single host or the appropriate value
for the source IP addresses.
The IP address of the sender of the incoming packet is bitwise ANDed with
this mask and then compared to the field ‘Source IP’.
Local Port Range
[AccessList_Start_Port]
[AccessList_End_Port]
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.
Protocol
[AccessList_Protocol]
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: The protocol field also accepts the abbreviated strings ‘SIP’, ‘MGCP’,
‘MEGACO’ and ‘HTTP’. Specifying these strings implies selection of the TCP
or UDP protocols, and the appropriate port numbers as defined on the device.
Packet Size
[AccessList_Packet_Size]
Maximum allowed packet size.
The valid range is 0 to 65535.
Note: When filtering fragmented IP packets, the Packet Size field relates to
the overall (reassembled) packet size, not to the size of each fragment.
Byte Rate
[AccessList_Byte_Rate]
Expected traffic rate (bytes per second).
Burst Bytes
[AccessList_Byte_Burst]
Tolerance of traffic rate limit (number of bytes)
Action Upon Match
[AccessList_Allow_Type]
Action upon match (allow or block)
Match Count
[AccessList_MatchCount]
A read-only field that provides the number of packets accepted / rejected by a
specific rule.
