This means that it has the web, ftp and telnet ports open. I would not
be worried unless you can change the config of the router via telnet and
from any IP address and you have not changed the default passwords.

I use smoothwall, which has the same feature, very useful as we have 5
people sharing my adsl connection and they all play different online
games. An absolute nightmare if I had to open each port individually.
