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.
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 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

Specify the source IP filter for this ACE.
■
Any
: No source IP filter is specified. (Source IP filter is "don't-care".)
■
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.
When "Host" or "Network" is selected for the source IP filter, you can enter a
specific SIP address in dotted decimal notation.
