If GLS is set using the hostname rather than an IP address, enable the "hostname translation function". If this function is enabled, even if you make the settings so that the hostname is changed using DNS on the system, you can change IP addresses by using a file (/etc/hosts) as GLS.
Confirmation method
Check the IP address settings of GLS. If the hostname has been set, check that the value for "Hostname resolution by file(h)" of the "hanetparam print" command is YES
