there should be a network setting section on your DVR program...check in there...you can see and configure...then move onto port forwarding. forget the dhcp set it to auto or just make sure the DVR is assigned DHCP correctly and has access to ur router. then port forward the port that is listed on the DVR network settings.
after you have correctly everything, www.whatismyip.com and connect to it.
