TCP: Select TCP to filter IPv4 TCP protocol frames. Extra fields for defining
TCP parameters will appear. These fields are explained later in this help
file.
• IP Protocol Value
When "Specific" is selected for the IP protocol value, you can enter a specific
value. The allowed range is 0 to 255. A frame that hits this ACE matches this IP
protocol value.
• IP TTL
Specify the Time-to-Live settings for this ACE.
■
zero: IPv4 frames with a Time-to-Live field greater than zero must not be
able to match this entry.
■
non-zero: IPv4 frames with a Time-to-Live field greater than zero must be
able to match this entry.
■
Any: Any value is allowed ("don't-care").
• IP Fragment
Specify the fragment offset settings for this ACE. This involves the settings for
the More Fragments (MF) bit and the Fragment Offset (FRAG OFFSET) field for
an IPv4 frame.
■
No: IPv4 frames where the MF bit is set or the FRAG OFFSET field is
greater than zero must not be able to match this entry.
■
Yes: IPv4 frames where the MF bit is set or the FRAG OFFSET field is
greater than zero must be able to match this entry.
■
Any: Any value is allowed ("don't-care").
• IP Option
Specify the options flag setting for this ACE.
■
No: IPv4 frames where the options flag is set must not be able to match this
entry.

■
Host: Source IP filter is set to Host. Specify the source IP address in the
SIP Address field that appears.
■
Network: Source IP filter is set to Network. Specify the source IP address
and source IP mask in the SIP Address and SIP Mask fields that appear.
• SIP Address
When "Host" or "Network" is selected for the source IP filter, you can enter a
specific SIP address in dotted decimal notation.
• SIP Mask
When "Network" is selected for the source IP filter, you can enter a specific SIP
mask in dotted decimal notation.
• DIP Filter
Specify the destination IP filter for this ACE.
■
Any: No destination IP filter is specified. (Destination IP filter is
"don't-care".)
