Parameter Description
Deny Inter User Traffic Denies traffic between untrusted users by disallowing layer-2 and
layer-3 traffic. This parameter does not depend on the deny-inter-user-
bridging parameter being enabled or disabled.
Default: Disabled
Deny Source Routing
Permits the firewall to reject and log packets with the specified IP
options loose source routing, strict source routing, and record route.
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.
Default: Disabled
Deny All IP Fragments Drops all IP fragments.
NOTE: Do not enable this option unless instructed to do so by a Dell
representative.
Default: Disabled
Enforce TCP Handshake
Before Allowing Data
Prevents data from passing between two clients until the three-way TCP
handshake has been performed. This option should be disabled when
you have mobile clients on the network as enabling this option will
cause mobility to fail. You can enable this option if there are no mobile
clients on the network.
Default: Disabled
Prohibit IP Spoofing Enables detection of IP spoofing (where an intruder sends messages
using the IP address of a trusted client). When this option is enabled,
source and destination IP and MAC addresses are checked for each
ARP request/response. Traffic from a second MAC address using a
specific IP address is denied, and the entry is not added to the user
table. Possible IP spoofing attacks are logged and an SNMP trap is sent.
Default: Enabled
Prohibit RST Replay Attack When enabled, closes a TCP connection in both directions if a TCP RST
is received from either direction. You should not enable this option
unless instructed to do so by a Dell representative.
Default: Disabled
Log ICMP Errors Enables logging of received ICMP errors. You should not enable this
option unless instructed to do so by a Dell representative.
Default: Disabled
Stateful SIP Processing Disables monitoring of exchanges between a voice over IP or voice over
WLAN device and a SIP server. This option should be enabled only when
there is no VoIP or VoWLAN traffic on the network.
Default: Disabled (stateful SIP processing is enabled)
