[Discuss] printer issue

[gaf.linux at gmail.com (Jerry Feldman)]

The issue you raise is privacy. If you use the isp provided gateway or your
own replacement, devices will get up addresses from that gateway's nat. If
you get a router, and set it up to manage your lan, you are insulating your
devices from the network. Of course, if you want a device accessible from
the outside, that is a different story.
