Back some time ago, months maybe, I went through the steps to install a new wireless router to work in tandem with my Centurylink modem/router (Actiontec PK5001A) and had nothing but trouble with the Asus AC1200 router. I finally gave up and boxed it up and put it in the closet. What I noticed shortly afterward was I no longer could communicate with my observatory computer via the web browser even though the LAN address and port number was valid. Checking the modem I can see the port was still forwarded but checking the port showed it as closed. In fact the only forwarded ports still working that had been forwarded were the ones on the wireless IP cameras installed in and around the observatory. I do have an account with No-IP to track my changing WAN address as mine isn't static. I also have several programs that communicate with the telescope automation system that do so through forwarded ports that do work now but did previously.
The home network consists of 5 desktop Windows computers, 1 tablet, 2 laptops, and several TVs, Dish network and so on. Windows systems are both Windows 7 Pro 64 bit as well as Windows 10 Pro 64. I use ESET antivirus and one of its newest features is network monitoring. From that I learned that there appear to be so LAN addresses I'm not familiar with and have no idea where there originated from. My LAN IP addresses all are 192.168.0.xxx and there no appear to be some new ones that are 192.168.50.xxx and 192.168.51.xxx. Pining these shows no returns. The router is the Actiontec PK5001A and additionally there are 3 switches, one in the observatory, one behind the living room entertainment center, and the main one in the basement. All are rated 10/100/1000 and are wired Cat5E. There is one wireless access point in the observatory for the wireless connections to the IP cameras.
I guess as a not well verse network person I'm looking for advice as to where to start and what I should do. I would really like to get port forwarding back on the wired network.
