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

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' 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]

The valid range is 0 to 65535.
Note: When filtering fragmented IP packets, the 'Packet Size' field
