DoS Settings



Set the limits based on your network specifications. Values that exceed your available bandwidth or server capacity may affect performance, while values that are too low may block valid requests.


  1. Go to PROTECT > Intrusion prevention > DoS & spoof protection.
  2. Select Apply Flag on the following under DoS settings:

    Source and Destination Destination
    SYN flood Dropped source routed packets
    UDP flood Disable ICMP/ICMPv6 redirect packet
    TCP flood ARP hardening
    ICMP/ICMPv6 flood
  3. Click Apply.


Ensure that DoS bypass rule is not added with wide range of source or destination networks that will reduce integrity of overall DoS protection.
