ASA 5506-X running as ASA only 9.13.1
My Exchange server (192.168.1.5) is unable to connect to the 192.124.249.xxx addresses because of a perceived SYN Attack
This is preventing my SSL certificates from working properly
Is there any way to whitelist these external IP addresses ? They are valid and part of GoDaddy's CRL list
Her are the stats from : show threat-detection statistics top
<Rank> <Server IP:Port> <Interface> <Ave Rate> <Cur Rate> <Total> <Source IP (Last Attack Time)>
