DVR login failed from internet (Logon Failed... error logging in from the Internet)

[CoyoteKG]

I was connect DVR in LAN.
IP of my DVR is 192.168.1.155. When i type that IP adress in IE, than appear logon.
I type pass "admin" and choose LAN (there is only that 2 options) and work! I can see my cameras.

But if I try do that from internet, appear massage LOGIN FAILED. I do port forward, type address from whatismyip... 109.94.161.78, than I have same logon window like from LAN.

Problem is that I can successfully login to my DVR from internet with that IP, but I can't log on, like I can from LAN computer. I tipe same password "admin", and choose "Internet" instead of "LAN" and apear message "Logon Failed..."

Please help

Tnx. Problem is because I was forward only "web port" 80, but I didn't some port called "Media port" which is set in DVR like 9000. When I was forwarded that port too, problem is solved.

tnx
