A geo-based IP mitigation dos attacked started against an internal IP address.
All internal addresses getting blocked as a geo location.
Traffic from internal addresses is arriving to the system. A geo location mitigation is configured for DosL7.
Whitelist the internal addresses. Note: Doing this prevents all types of mitigation from these IP addresses.
RFC1918 is not considered as a geolocation and during geolocation mitigation, traffic from these IPs will not get dropped. These IP addresses can still get mitigated during other mitigations. A new internal parameter, DOSL7.geolocation_drop_private_ips, default disable, is introduced. When enabled, the system changes this behavior so internal IP addresses do mitigate in the geolocation mitigation.
