One of our readers is reporting a fairly recent increase in ICMP packets hitting his firewall. If you're seeing the same we'd like some data:

  • on the importance and timeframe of the increase;
  • the type of ICMP packets you're receiving;
  • some idea of how it correlates (sweeping your address range, just hitting one IP, coming from all over, coming from specific hosts, ...);
  • if possible a small sample of some out of the ordinary packet captures.
As always you can upload your results through our contact form.
