You do not execute the file, you poke a one into it.

First, see how it's currently set with a:

  cat /proc/sys/net/ipv4/ip_forward

If it's "1" then you're all set.  Stop right here.

If it's a zero ("0"), then sent it to one like this:

  echo 1 > /proc/sys/net/ipv4/ip_forward

The file is not a "real" file (none of the files are real in /proc).
/proc is a window into the running kernel.  That's why it appears
to be zero bytes long in size.
