External access to webcam [GL-AR300M]

I’ve GL-AR300M-Ext and I connected to it a webcam, so I can use webcam from router interface.

is possible to see webcam outside home ? so can I access to webcam though internet ?

You can enable wan access on ui at first, and then use the ddns to access.

thank you for your answer

have I to enable wan access from simplified or complete ui?

have I to download anything to use DDns ?
