I have 4 IP cams around the out side of my home. (for security.) that have web servers as their GUI, I have them set to different ports I.E 82-83-84-85 and all of them support UPnP. What I have set up is my cable modem form the ISP is both a modem/IP Phone/wireless router. an apple time capsule Gen2 with 802.11AC set up in bridge mode. everything works fine but one thing the controller for the badge access system does not support changing the port number of its internal web server like the IP cams and does not support UPnP. The way I access my cams from remote is that the cams send me a email any time the external IP changes and all I have to do to access any one of them is to add a " : " the the port number of the cam I want to connect to and log in. The problem is that if I want to remote admin my card access system I can't it conflicts with the cable modems remote login. ( I really Don't want to disable.) What can I do?
