TCP/IP Settings

TCP/IP Settings

This screen allows you to configure settings to connect the machine to a TCP/IP environment and use it.

The IP address can be checked and its acquisition method can be set, the DNS server can be set in the current operating environment, and the IPsec setting can be made based on the safety communication technology as follows.

*1:

If Auto Input is selected, the following settings are available.
-DHCP Settings
-BOOTP Settings
-ARP/PING Settings
-AUTO IP Settings
However, changing the selection from Auto Input to Manual Input invalidates the settings made for DHCP Settings and BOOTP Settings. Also, changing from Manual Input to Auto Input validates the following settings.
-DHCP Settings
-BOOTP Settings
-ARP/PING Settings
-AUTO IP Settings

*2:

If IPv6 Settings is set to OFF, this function is disabled even when IPv6 Auto Settings is set to ON. In Web Connection, the drop-down list of IPv6 Auto Settings is grayed out.

*3:

Selecting OFF for IPv6 Auto Settings enables the setting change of Global Address Prefix Length and Gateway Address.

*4:

If the following address range is specified, it causes an error.
fe80:: - febf:ffff:ffff:ffff:ffff:ffff:ffff:ffff
ff00:: - ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff

*5:

This can be set if Encryption Algorithm is set to AES-CBS.

*6:

This can be set if Authentication Algorithm is set to SHA-2.

*7:

Available only for the range from fe80: 0: 0: 0: : to fe80: 0: 0: 0: ffff: ffff: ffff: ffff.

*8:

Up to 253 one-byte characters including periods can be entered for the host name.

To enter 64 characters or more, you need to use periods (.) to separate the characters.

*9:

You can use the advanced settings in the Administrator Mode of Web Connection (for details, refer to TCP/IP Setting).

*10:

Only one IP address, not a range, can be permitted/denied in three ways.

For example, to permit/deny 192.168.11.22 only, enter:

192.168.11.22 - 0.0.0.0

0.0.0.0 - 192.168.11.22

192.168.11.22 - 192.168.11.22
