ILOGMODE Setting of IP address block mode
Lv.1 Details To set all protocols or TCP/UDP/ICMP unicast as the target of IP
block.
When 0 is set, the machine responds to ARP, ICMP multicast and
broadcast which have no direct relation, and consequently the
number of logs is increased.
When 1 is set, the machine filters TCP, UDP and ICMP unicast only.
Use case Upon user's request
Adj/set/operate method 0 to 3
0: All protocols support mode
1: TCP/UDP/ICMP unicast support mode
2, 3: Not used
Default value 0
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
Display/adj/set range 0 to 48
0: 1 minute (special mode)
1 to 48: 1 hour to 48 hours
Default value 1
5
IPTBROAD Set to allow broad/multi cast 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 Enter the setting value, and then press OK key.
Display/adj/set range 0 to 1
0: OFF, 1: ON
Default value 0
PRNIPBLK ON/OFF of IP address block function
Lv.1 Details To set ON/OFF of IP address block function.
When 1 is set, "IP Address Range Settings" and "RX/Print Range"
screen is displayed on the Control Panel.
Use case When using the IP address block function
Adj/set/operate method Enter the setting value, and then press OK key.
Display/adj/set range 0 to 1
0: OFF, 1: ON
Default value 0

IPMTU Setting of MTU size
Lv.1 Details To set MTU size of network packet.
This item is used when performing SEND communication between
locations 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 byte, 2: 700 byte, ..., 9: 1400 byte, 10: 1500 byte
Unit 100 byte
Default value 10
