Management Setup
For security concern, it's better for you to limit the clients that are
allowed to access the router's management interfaces. If you only allow
specific internal or external IP addresses to access the router's
management, Only these IP addresses or subnets (ranges) you listed
can access the router's menus. In order to assure you will not lose the
ability to access the router management yourself (normal routing still
works), you HAVE TO remember to include your own local IP
address/subnet too.
