Use an IPv4 network for correct logging.• When searching a device outside the router via SMB, directly specify the address. Multicasting issupported only within a local link (FF02::1).• In an IPv6 network environment without a DNS server, authentication fails when a computername is specified in the SMB server settings for SMB authentication. Specify an IPv6 addressdirectly as the authentication server's computer name.
