1 - Destination IP Address
The Destination IP Address option defines a hole in the firewall for the IP address (or range of addresses) for frames
outbound from this P1700 to a destination on the network in question.
The IP address consists of 4 eight-bit fields, each field is specified by a decimal number and the fields are separated by a
decimal point (e.g. 92.3.1.10). Each decimal number must be less than or equal to 255 (the maximum decimal value of
an 8-bit binary number).
Default:
[none]
2 - Destination Mask
The Destination Mask option defines the address mask to be used on the Destination IP Address defined in option 1
for this entry. To have the firewall entry apply to an individual IP address a mask of none should be used.
The address mask consists of 4 eight-bit fields, each field is specified by a decimal number and the fields are separated
by a decimal point (e.g. 92.3.1.10). Each decimal number must be less than or equal to 255 (the maximum decimal value
of an 8-bit binary number).
Default:
[none]
3 - Source IP Address
The Source IP Address option defines a hole in the firewall for the IP address (or range of addresses) for frames
inbound to this P1700 from the network in question. The default setting of this option allows all IP addresses on this
network to send frames out through the P1700. Setting specific source IP addresses allows for greater restrictions on
who can access external networks.
The IP address consists of 4 eight-bit fields, each field is specified by a decimal number and the fields are separated by a
decimal point (e.g. 92.3.1.10). Each decimal number must be less than or equal to 255 (the maximum decimal value of
an 8-bit binary number).
Default:
[all]
4 - Source Mask
The Source Mask option defines the address mask to be used on the Source IP Address defined in option 3 for this
entry. To have the firewall entry apply to an individual IP address a mask of none should be used.
The address mask consists of 4 octets and is represented by 4 fields separated by periods ("."), where each field is
specified by a decimal number (e.g. 255.255.255.0). Each decimal number must be less than or equal to 255, that is the
maximum value of each 8-bit field.
Default:
[none]
5 - Protocol Type
The Protocol Type option defines the protocol type to allow through the firewall for this entry. The protocol type may
be defined as TCP, UDP, or any other protocol type. Other protocols are defined as a valid IP protocol type in hex.
Default:
[TCP]
Choices:
TCP, UDP, (any protocol type number in hex)
