I am unable to make a number of the changes in "Securing your Router" and its not clear why, but I am guessing that some of the options listed are no longer correct.
Edit: Thats what seems to have happened.
The changes are small.. and involve the syntax of disabling/enabling mac-services and formerly allowed-addresses, now just addresses.
Could you update it to reflect current syntax?
Also, what is the minimal amount of info a router can be configured to supply at its interface with the internet provider, and still work?
