No Open Ports

Posted by tomwiles at 10:28 PM on March 29, 2013

It started out with me not being able to remote in properly to multiple devices on my home network while I was traveling for work. I got home a week and a half later, thinking I’d probably just need to reboot my DSL router and perhaps a few other network devices and everything would quickly be back to normal.

Well, not so fast. It seems that my trusty and heretofore reliable telephone-company-provided Siemens Speedstream 4200 DSL router had somehow lost it’s configuration data – things like the phone number, the username and the password. I put all of that back in, and everything seemed to return to normal. That is, until I decided to see what would happen if I pulled the power plug. To my chagrin, it suffered yet another total identity crisis. Something must be wrong with it.

Hummm. The DSL installer had given me a second modem just in case the first one didn’t work when he initially got the DSL installed a couple of years ago, a unit designated as Sagem Fast 1704. I pulled it off the shelf and plugged it in to my system. This one is not nearly as user-friendly as the Siemens Speedstream 4200. After an extended amount of wrangling with it I got it working, but I still couldn’t get my remote IP camera, a Loftek CXS 2200 (an excellent inexpensive IP camera by the way) to work. I was doing everything exactly right, and it was still no go. The Loftek IP camera could not connect to the outgoing email server, and no matter what I did I couldn’t remote in to the camera itself from outside of my home network.

After wasting hours trying to determine what I might be doing wrong, I finally got the idea of going to a website where I could scan my home network IP address for open ports, and I immediately discovered what the problem was. Even though I was enabling port forwarding in the Sagem Fast 1704 DSL router, virtually ALL ports were closed. No matter what I did, unless I’m missing something, the ports cannot be opened on this router.

The moral of the story is if you are having problems with your router and port forwarding, potentially save yourself a bunch of time and go to a site such as http://www.yougetsignal.com/tools/open-ports/ and find out if the ports you are working with are actually open or not.

Additionally, I took advantage of Geek News Central’s DynDNS discount offer and quickly set up an inexpensive account that enables me to easily view my Loftek IP camera without messing around with finding what my dynamic IP home IP address has switched to.  With a camera app on my phone and other mobile devices, I can simply open up the app and always get a live view without having to go through any additional steps.

Madison River Communications Fined For Blocking VoIP Access

Telecommunications provider, Madison River Communications, was chastised by the Federal Communications Commission (FCC) last week and required to unblock network ports that were closed to prevent connections from customers using Voice over IP (VoIP) telephone connections.
