Most of these ISPs already provide a home gateway (often integrated with the DSL model or cable modem), and it only has to work with that brand! So I favour 172.16/12 or 224/10. -- ] He who is tired of Weird Al is tired of life! | firewalls [ ] Michael Richardson, Sandelman Software Works, Ottawa, ON |net architect[ ] [email protected] http://www.sandelman.ottawa.on.ca/ |device driver[ Kyoto Plus: watch the video <http://www.youtube.com/watch?v=kzx1ycLXQSE> then sign the petition.
