It's unreasonable to expect us to look through an 1,800 line script for a
problem like this.  You really should trim it down to the simplest script
that expresses the problem you're encountering.

That said, I'll note that the only references to $ip_hdr$id (or even $ip_hdr)
are commented-out, so certainly aren't going to work!
