Not that explicit... I'm using NetBSD-1.6 here. Look at this manpage. I just
compared to the current manpage on www.netbsd.org, where there really is a
large extra paragraph "Setting up NAT with MSS-clamping", which is nonexistent
in the 1.6-manpage.

I think with the newer manpage with this extra paragraph, this is not really
necessary. I just tend to use the installed manpages, and due to some mails
about instabilities of 1.6.1 i saw here a while ago, i'm still using 1.6, where
this paragraph, which really can't be overseen, is just not present.
Maybe my fault. Or just forget my states about "this should be included", as it
seems to be included somewhen after 1.6.
BTW: after using some "keep frags" in ipf.conf, this really works fine. As
usual, great work! :)
