ProCurve 1810G-24 Auto DoS problem

[Ivo Suste]

Enabling Auto DoS option on 1810G-24 switch blocks netbios traffic and messes up the communication of FTP client.
It took me some time to realize where the problem was when all networked MFDs lost the ability to send to server shares, and Windows native FTP client (from CMD) was not able to receive results of ls command from a public FTP server.

Looking for a solution I have realized that this problem existed a year ago. However, HP did not fix it until now.

This really is quite cool feature ..... </end of irony>

from what we saw, it blocks traffic which have same source and destination port numbers .... especially UDP datagrams, so it's breaking things like NTP servers sync, asterisk trunk etc......

we turned that off after we spend like 3 days to investigate ..... burn that checkbox....
