I am using DSL-2750U as router (192.168.1.1). dyndns configured. if trying to connect using Hostname from internet it shows router's page only. DVR ip 192.168.1.50 port 8080. configured virtual server on 8080, port triggering to 8080 TCP and DMZ to 192.168.1.50.
I tried Simple Port Forwarding Tool also. But same thing is happening.
