With recent changes to PF, the default capture size (68 bytes as seen above) is insufficient. Try adding "-s128" to capture more of the packets and you should see an improvement. - -- David DeSimone == Network Admin == fox@verio.net "This email message is intended for the use of the person to whom it has been sent, and may contain information that is confidential or legally protected.
