Hi all on the forum

I am a plusnet customer and I need help please........ I have a Plusnet 2704n router and an Edimax IC 3005 ip security camera.
I had a look at the instructions to enable me to log onto the ip camera from anywhere using the internet and view my camera live stream.
I know I have to open ports using port forwarding, but I cant find the right instructions for my router

Could someone give me a walk through please.
Thanks a million.
Cheers
Alb
