Bonjour, We are facing several syn flood attacks since the last 2 weeks. We use IPVS boxes in top of our infrastructure directly after our routers. We use IPVS with the option âNetfilter connection trackingâ. So, our boxes (2 boxes in active/backup) made filtering and load-balancing. We use IPVS in NAT mode and a 3.0.36 kernel. For the moment, we reduce effects of syn flood attacks with our router
