I don't know the specific terminology to use, so bear with me.
I have the Xfinity X1 package with the DPC3939 Gateway Modem. I have a security camera management page that simply runs over port 80 and a camera that runs on port 1234 (as an example). With the proper port forwarding in place, I can successfully access the page and camera from an outside network, however while I am on my WiFi or LAN, I cannot access the pages as I normally would by going to »
webpage.com as it seems like there is some type of issue with LAN requests going out and coming back through the WAN.
Has anyone else with this modem experienced this, maybe anyone that is running any type of web server? I know I read something about it somewhere that this modem/gateway doesn't support lan to wan requests, but I'm at a loss for finding that article.
