Figure 1 Specify the IP address to allow connection

The description rules are as follows.

  • If this setting field is blank, logon restriction by IP address is not performed.
  • Multiple IP addresses can be enumerated by comma in one setting field.
  • The IP address notation corresponds to (regular expression expression of Java).

Handling of commas7.9

  • Commas in curly braces {} and square brackets [] and commas after backslash \ are not treated as delimiters.
  • When an IPv4/IPv6 IP address is specified, it is not treated as a regular expression.

With this rule, for example the following format is possible.


:: 1 is IPv6 IP address (you can omit 0: 0: ... by writing ::), is the IPv4 IP address.

By setting the following in, the log at the time of checking is output.

When this setting is made, please test that it is not accessed from other than the specified IP address. In particular, when describing an IP address using a regular expression, be sure to check whether it will be accessed from an unexpected machine due to a mistake in the expression of a regular expression.
