IPFW DDos Attack to port 443

E

Ercan Deger

Hello All,


I’m using my FreeBSD device as a gateway, and lately I’ve been receiving a large number of attacks on port 443 from many different IP addresses. I have web server behind gateway. After some time, I can no longer access the device via SSH or other methods. I’m using IPFW as the firewall and kernel NAT. When I remove the NAT rule, the system starts working normally again. What should I do?

Thanks for your help
