 Date:  7 Sep 2004 09:14:12 -0700
Fragged packets allowed in from LAN:

@6 pass in quick from 10.0.0.0/8 to any \
  keep state keep frags group 100

Fragged packets allowed in from WAN:

@1 pass in log quick from any to any \
  keep state keep frags group 200

Return packets blocked from www.netbsd.org (204.152.190.12):

Sep  7 08:52:36 bl0ck ipmon[68]: \
  08:52:35.742487 ng0 @0:16 b 204.152.190.12 -> 209.180.174.155 \
  PR tcp len 20 (1476) frag 1456@24 IN

This is really buggin.  And www.netbsd.org continues to be the
only site we have this trouble with.

WAN is set up with PPPoE, an adsl connection.

Thank you for all help, suggestions.
