When connecting the copy destination system with the network different from the network in the copy source system, modify the static route information including the default gateway according to the environment of the destination environment.
For RHEL8, modify the gateway address that is described in the /etc/sysconfig/network file, in the /etc/sysconfig/network-scripts/route-interface name file, or in the /etc/sysconfig/network-scripts/ifcfg-interface name file if necessary.
For RHEL9, modify the gateway address by the "nmcli connection modify" command if necessary.
