My DNS servers are getting alot of ICMP type-3/code-3
traffic. This is Destination unreachable/port unreachable.
3 Destination Unreachable [RFC792]
Codes
0 Net Unreachable
1 Host Unreachable
2 Protocol Unreachable
3 Port Unreachable
This happens at random times, but in large bursts (5-10 +
packets from specific hosts).
Why are my DNS servers (Bind 8.1.2) receving these packets?
Thanks!
