I want to access my TD-8968 v3 remotely. I tried mrinal's video but there are some problem

1. I am not getting option of setting port from remote access like mrinal does in the video @ Managment>Access Control>Remote Access

2. I have added my noip's host name in Advence Setup>DNS>DDNS.

3. As the default port is 8080 so I treid 8080 after my hostname of noip, I am still not able to access my TD-W8968 v3 from different location, I used port 8080 after my host name, like "Hostname:8080" but I am unable to access my TD-W8968.
