[Modus] OT: Allowing SMTP on an ISP's Network + Nachi (Welchia) worm

[Frank M. Cook]

<As an ISP, what has everyone done to guard against bandwidth hogging infected machines (the latest seems to have been the Nachi or Welchia worm outbreak)?>   I had that problem although I've changed routers since.  the problem was my old router was having every computer on the network respond when someone pinged the broadcast address (top number in the subnet).  I solved it by adding a filter at the router turning off pinging just on the top address.  I now have a Cisco router that doesn't seem to have the issue.   Frank M.
