IPTBROAD 1 Set to allow broad/multicast TX
Detail To set whether to allow transmission of broadcast packets and multicast packets.
Transmission of broadcast packets and multicast packets is allowed without specifying an
exception address. It is allowed within the device even if it is rejected in the default setting of the
IPv4/v6 transmission filter.
Set 1 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: Allowed, 1: Prohibited, 2 to 5: Not used
Default Value 0
PFWFTPRT 1 Set of RST reply at IP filter FTP SEND
Detail 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 decreased.
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 1 Setting of MTU size
Detail To set MTU size of network packet.
Use this mode when performing SEND communication between locations connected with Ethernet
in a field environment where MTU black hole problem occurs.
Use Case - When preferring to reduce the MTU size
- 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 byte
Default Value 10
Supplement/Memo MTU: The maximum size of data unit that can be transmitted with a single transfer (1 frame) over
network.
MTU black hole: A problem which occurs when ICMP packets are filtered by firewall, etc. (Since
no message is sent to the sender, the sender does not notice that the packets are discarded and
timeout occurs.)
