I'm sure this is an easy one for router jocks, but I'm the new owner of a Cisco 804, and the port test at grc.com keeps telling me that my telnet (23) port is open. Have tried numerous fixes from the manual and off the web to no avail. I'm accessing the router through the serial monitor. Router password has been changed and "supersecreted". Should I worry? If so, any tips for how to close the damn thing?
One would think they could find such info in the docs/on Cisco website, but no joy.
Thanks a bunch.
