While under a DDOS attack the firewall hit its maximum number of connections and grinded to a halt. We were unable to connect to it and traffic that was routed between the DMZ and Internal interfaces was also stopped. My question is it possible to change the max number of connections or altleast always allow the Firewall Admin to connect? Also can we not make this a soft limit or limit it to External connections? The hardware should have been able to handle the traffic it was the software limit that cause the problem.
We are running Astaro v5.19.
Thanks for your insights
