Port forwarding

> After trying 5 times [...]

   You could do whatever you're doing any number of times, but, with my
weak psychic powers, I still couldn't see what you did.

> [...] I am still unable to forward my router [...]

   "unable" is not a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

> [...] so I can access my dvr when not at home.

   I also have no idea what your "my dvr" might be, or how you access it
when you _are_ "at home".

> Please help.

   You first?

   Based on approximately no useful information, I don't know how
helpful it might be, but, for the usual problems with port forwarding,
