IPsec IKE Session Flood

Post by gparedes » Mon Nov 15, 2021 7:40 pm

Hi, a couple of weeks ago I am having IPsec IKE Session floods from different ip addresses, the behavior is the same in 3 softether servers, when viewing the logs the size is up to 1gb and in the case of a vps this consumed 90% bandwidth (1 Terabyte) in a couple of hours until I received notification. I think it is a problem similar to the one mentioned here (viewtopic.php?t=65912), for IPsec IKE Sessionel, at the moment I block any ip that is more than a certain number of times in the log and it worked, but I would like to know if from softether there is any option for this, for your help thank you very much, log looks like:
