Do not take this personally but I find it exceedingly disturbing that you should use the ml as a documentation storage space.

You really should store this kind of information internally, such as a comment in your pf.conf and/or a wiki.

Additionally, you may find the correct syntax for rdr rules in man pf.conf, so you'll always have an example handy.
