Increase in tcp traffic from spoofed source to bogon?

Thu Sep 25 21:40:50 UTC 2003

Is it all to 135 ?  I  drop lots of that at my border.  Each time I traced 
it back to the customer, it was some infected machine that was not being 
natted for various reasons.

e.g.

Deny TCP 172.16.4.1:4616 192.100.103.4:135

We also see the odd ntp request.  Is it bogon as in RFC 1918 or bogon as in 
not yet allocated / routed ?
