I've been searching for hours, and apparently this is an obscure model of router or something, because there are no guides on how to port forward this model of router. I can't even find the port forwarding page! I use this IP to connect: 192.168.100.1, and this is what the page looks like: http://imgur.com/wu70Yi2 I've tried navigating this place, but all that I see is displays. What do I do to forward a port?
2It's a cable modem not a router. There is no port forwarding on cable modems. – DavidPostill – 2014-11-09T21:24:53.737
Might I also have a router, or could I only have Modem? – Minecat40 – 2014-11-09T21:29:13.243
Please read the manual for your device - http://www.speedguide.net/images/hardware/motorola/sbv5121_ug.pdf, page 33 "The SBV5121 VoIP cable modem supports several multiple user configurations. Along with an optional hub or router, it can serve as an Internet gateway for up to 31 computers. Not all service providers support multiple user service. For information about multiple user service, contact your cable provider." – DavidPostill – 2014-11-09T21:33:00.733
