nonosystem

Hello from paris… I got an h264 dvr machine and it’s connect ok with my internet explorer (old version with active_x)…right.. But when I try to connect by the web, I did not connect on my router port…(i call my wan adress:port) Is it necessary to pass by a dyn dns to perform that or simply goes xx.xxx.xxx.xxx:port to connect ?? Have you exemple of simple extrernaly configuration connections that work well.. Thank u….
