Here is a thread from a few weeks ago.... might answer your question.. Tv
-------------------------------------------------------- The packet size cannot be changed in WhatsUp Gold v8.01. The ICMP packets used by WhatsUp Gold have a data size of 50 bytes, giving a total packet size of 78 bytes when headers, etc, are factored in. Now, this is smaller than the 92 bytes that you cite for the nachi/welchia worm. So your filtering should work in theory. Could you try and set the cut-off somewhere between (say) 80 and 88? Anyway, I logged a request into our database a couple of days ago for the WhatsUp Gold ICMP packet size to be reduced to 64 bytes (minimum Ethernet packet size). I will update the database so that it has your report as well.

I am wanting to implement traffic shaping to drop 92 byte icmp packets used by the nachi/welchia worm to scan for vulnerable hosts and as soon as I implement this change my whatsup maps show all my devices down.

We have been blocking the Nachi virus which looks for a 92 byte ping packet. At the same time we can ping our equipment from a DOS prompt on the Whatsup server, but whatsup cannot ping that device, it returns a timeout error. Basically, I can ping a device from anywhere BUT from within Whatsup.
