I recently had an interesting problem. I kept getting warnings from my router about a 3rd party router being connected. You might say, “How does your router warn you?” While browsing the web my router would force a redirect to a web page (hosted by the router’s web server) instructing me that a 3rd party router was detected and I could put it in the DMZ. I closed it. I think the message came up again later and one of my kids hit RESOLVE. The router then proceeded to put my iMac in the DMZ!
My iMac didn’t have the firewall on because I was troubleshooting problems with syncing my AT&T Tilt (Mac syncing is not for the faint of heart). All of a sudden I’m getting email bounce messages from all over – I think my Mac somehow was being used to send canned ham. I couldn’t figure out how to stop this DMZ feature from happening. I disconnected my Mac and my laptop was the next silicon offering to the DMZ.
Time for U-Verse support. I called before I left work because I didn’t know the hours of support, seems they are available 24×7. The tech said he’d call me back when I got home and setup a callback time. They called and tried to configure my router remotely but was unable to see my device configuration. Since he wasn’t familiar with my issue he quickly handed me off to the next level of support. This person was an expert in the configuration and had no trouble connecting and turning off the DMZ (just do a restore default settings under Firewall – I was looking for a check-box). Then he set it to not warn me anymore if it detects that condition (which he wasn’t sure why it would do that, I was the first one he had heard of). I asked if there was a way to just use my old linksys router for wi-fi. Answer? Sure – just go to your TV channel 411 and watch the video HOW-TO! Very helpful, 10 minute call. Kudos guys.
If you got the same message and don’t want to be bothered (or having someone click RESOLVE) go to this URL:
http://192.168.1.254/MDC
This is the more advanced management console for your router. Go to Local Network on the left, then Configuration. Scroll down on the right side and you’ll see an option “Display router behind router warning”. Just uncheck it and be happy.
