Well do you have port forwarding of port 23 to a particular computer? If so, your probably getting a response from that computer. I don't see why they would allow telnet on the router and not give a option to turn it off, since it can be a possible security vulnerability. As for getting a "official" help, your in the wrong place. No Dlink employee's post or monitor. If you want something official, need to call Dlink.
