Note: When using IP address pair switch, high-order protocol port No. pair switch, or IP
address high-order protocol port No. synchronization switch, pay attention to the
following:
(1) Whenusing IP address pairswitch for "-ip_pair": When using source IP address and
destination IP address for range specification, set notto overlap the source IP address
range and destination IP address range. If these ranges overlap, take either ofthe
following actions:
Set pair switch to -ip_pair_off; -port_pair_off; -pair_synchronized.
Divide the definition offilter list information so as notto overlap the IP addresses.
(2) When using high-order protocol port No. pair switch for "-port_pair": When using
sourcehigh-orderprotocolport No.and destinationsource high-orderprotocolport No.
for range specification, set notto overlap the source high-order protocol port No. and
destination source high-order protocol port No. range. If these ranges overlap, take
either of the following actions:
Set pair switch to -ip_pair_off; -port_pair_off; -pair_synchronized.
Divide thedefinitionof filter list information soas notto overlap the high-order protocol
port.
(3) When using IP address pair switch, high-order protocol port No. pair switch, or IP
address high-orderprotocol portNo. synchronization switch by combining them, use
them in the combination shown in Tables Table 1-60 and 1-61. The setting values of an
upper protocol port number’s pair switch and IPaddress upper protocol number’s
interlock pair switch arevalidated when 6(TCP) or 17(UDP) is defined in the upper
protocol number. The setting values of an upper protocol port number’s pair switch and
IPaddressupperprotocol number’s interlockpair switch are invalidatedwhenthe upper
protocol number is undefined or when numbers other than 6(TCP) or 17(UDP) are
defined in the upper protocol number.
