ILOGKEEP Set of IP address block log hold time
Lv.1 Details To set the retention time from the log time of IP block.
When access is made again from a same IP address which was
blocked before, if it is within the retention time of the previous log, its
log is not recorded.
If access is frequently made from a same IP address, the log record
of the UI might be filled with its logs.
If the user considers that a single log for a same IP address is
enough, set the longer retention time.
Use case Upon user's request
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range 0 to 48
0: 1 minute (special mode), 1 to 48: 1 hour to 48 hours
Default value 1
IPTBROAD Set to allow broad/multicast TX
Lv.1 Details To set whether to permit transmission of broadcast packets and
multicast packets.
Transmission of broadcast packets and multicast packets is
permitted without specifying an exception address. It is permitted
within the device even if it is rejected in the default setting of the
IPv4/v6 transmission filter.
Set "1: Disabled" when the user does not want to send them.
Use case Upon user's request
Adj/set/operate method Enter the setting value, and then press OK key.
Display/adj/set range 0 to 5
0: Enabled, 1: Disabled, 2 to 5: Not used
Default value 0
PFWFTPRT Set of RST reply at IP filter FTP SEND
Lv.1 Details When FTP SEND is executed using an IP filter by which packets
from a specific remote PC are rejected, SYN is returned to the port
113 if the PC supports authentication of the FTP port 113. However,
since the IP filter blocks the packets, the block logs are increased
and the performance is lowered.
When 1 is set, RST is returned to the port 113 without blocking
packets.
Use case When executing FTP SEND against the OS which supports
authentication of the FTP port 113 while the IP filter is enabled
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range 0 to 1
0: OFF, 1: ON
Default value 0

IPMTU Setting of MTU size of network packet
Lv.1 Details To change MTU size of network packet.
Use this item when performing communications between locations
(such as SEND) connected with Ethernet in a field environment
where MTU black hole problem occurs.
Use case When MTU black hole problem occur
Adj/set/operate method Enter the setting value, and then press OK key.
Caution With IPv6, use of MTU which size is less than 1280 bytes is not
recommended by RFC. Therefore, when setting IPv6 to ON and MTU
to 7 or smaller, communication using IPv6 may not be available.
Display/adj/set range 1 to 10
1: 600 bytes, 2: 700 bytes, ..., 9: 1400 bytes, 10: 1500 bytes
Unit 100 byte
Default value 10
Supplement/memo MTU: A unit of transmission showing the maximum value of data
which can be sent per 1 transfer (1 frame) in a network
MTU black hole: A problem which occurs when ICMP packet is
being filtered by firewall, etc. (Since the message does not reach the
sender, the sender is not aware of the packet being lost, which then
results in time-out.)
DDNSINTV Set of DDNS periodical update interval
Lv.1 Details The registered contents are deleted in an environment where the
DNS server settings are deleted at intervals.
To set the interval of DDNS periodical update for not deleting the
registered contents.
Use case When the DNS server settings are deleted at intervals
Adj/set/operate method Enter the setting value, and then press OK key.
Display/adj/set range 0 to 48
0: No periodical update, 1: 1-hour interval, 2: 2-hour interval, ..., 47:
47-hour interval, 48: 48-hour interval
Unit 1 hour
Default value 24
Supplement/memo DDNS (Dynamic Domain Name System): A system to dynamically
register and manage the IP addresses which are dynamically
allocated and their host names
