You should not enable this option unless instructed to do so by a n Aruba representative.Įnables logging of received ICMP errors. When enabled, closes a TCP connection in both directions if a TCP RST is received from either direction. Possible IP spoofing attacks are logged and an SNMP trap is sent.

Traffic from a second MAC address using a specific IP address is denied, and the entry is not added to the user table. When this option is enabled, source and destination IP and MAC addresses are checked for each ARP request/response. You can enable this option if there are no mobile clients on the network.Įnables detection of IP spoofing (where an intruder sends messages using the IP address of a trusted client). This option should be disabled when you have mobile clients on the network as enabling this option will cause mobility to fail. Prevents data from passing between two clients until the three-way TCP handshake has been performed. NOTE: Do not enable this option unless instructed to do so by a n Aruba representative.Įnforce TCP Handshake Before Allowing Data Note that network packets where the IPv6 source or destination address of the network packet is defined as an “link-local address (fe80::/64) are permitted. Permits the firewall to reject and log packets with the specified IP options loose source routing, strict source routing, and record route. This parameter does not depend on the deny-inter-user-bridging parameter being enabled or disabled. This option can be used to prevent traffic, such as Appletalk or IPX, from being forwarded.ĭenies traffic between untrusted users by disallowing layer2 and layer3 traffic.
You can configure user role policies that prevent Layer-3 traffic between users or networks but this does not block Layer-2 traffic. Prevents the forwarding of Layer-2 traffic between wired or wireless users. Recommended value is 100 frames per second. Rate of misbehaving user’s inbound traffic, which if exceeded, can indicate a denial or service attack. Valid range is 1-255 requests per second. Number of TCP or UDP connection requests per second, which if exceeded, can indicate a denial of service attack. Valid range is 1-255 messages per second. Number of TCP SYN messages per second, which if exceeded, can indicate a denial of service attack. Number of ICMP pings per second, which if exceeded, can indicate a denial of service attack. See IPv6 Support for information about configuring firewall parameters for IPv6 traffic. To set these options in the CLI, use the firewall configuration commands. To set these options in the WebUI, navigate to the Configuration > Advanced Services > Stateful Firewall > Global Setting page and select or enter values in the IPv4 column. Table 1 describes optional firewall parameters you can set on the controller for IPv4 traffic. Understanding Global Firewall Parameters Understanding Global Firewall Parameters
