When a DOS profile configured with both Geolocation allowed IPs and Behavioral Detection accelerated/TLS signatures is assigned to a Virtual Server, no validation error is raised. The error only appears on a subsequent configuration reload, config sync, or when modifying the DOS profile after assignment.
The invalid configuration is silently accepted, potentially causing config sync failures or configuration load errors during a subsequent reload or failover event.
1.A DOS profile has Geolocation allowed IP entries configured 2.The same DOS profile has Behavioral Detection accelerated or TLS signatures enabled 3.The DOS profile is assigned to a Virtual Server for the first time
