> How do I connect my securety cameras with port forwarding?

   With my weak psychic powers, I have little to no idea what your
router is, or what your (unspecified) "my securety cameras" might be.

   You also seem to have missed the ORBI forums:

      https://community.netgear.com/t5/x/ct-p/home-orbi

But, even there, a better description of your gizmos (actual maker and
model number, firmware version, and so on) couldn't hurt.

   A simple Web search for keywords like, say:
      camera port forwarding
might find a page or two, too.  Most routers handle this stuff in very
similar ways, so it should be possible to translate almost any example
to your (unspecified) ORBI router.
