I can't make a connection do the DNS-Service from my router "Technicolor TG588v".



I didn't make any configuration with telnet because i have no access with telnet. But on the router i can use the Service "gnudip". Does it works with the Service?

The GnuDIP option does not work with Technicolor TG588v. We suggest that you follow instructions at https://www.dynu.com/DynamicDNS/IPUpdateClient/Technicolor to modify the configuration file using Telnet and use the service.
