13.9. Miscellaneous Settings
UDP Source Port 0
How to treat UDP packets with source port 0.
Default: DropLog
Port 0
How to treat TCP/UDP packets with destination port 0 and TCP packets with source port 0.
Default: DropLog
Watchdog Time
Number of non-responsive seconds before watchdog is triggered (0=disable).
Default: 180
Flood Reboot Time
As a final way out, NetDefendOS automatically reboots if its buffers have been flooded for a long
time. This setting specifies this amount of time.
Default: 3600
Max Connections
Packet re-assembly collects IP fragments into complete IP datagrams and, for TCP, reorders
segments so that they are processed in the correct order and also to keep track of potential segment
overlaps and to inform other subsystems of such overlaps. The associated settings limit memory
used by the re-assembly subsystem.
This setting specifies how many connections can use the re-assembly system at the same time. It is
expressed as a percentage of the total number of allowed connections. Minimum 1, Maximum 100.
Default: 80
Max Memory
This setting specifies how much memory that the re-assembly system can allocate to process
packets. It is expressed as a percentage of the total memory available. Minimum 1, Maximum 100.
Default: 3
Max Pipe Users
The maximum number of pipe users to allocate. As pipe users are only tracked for a 20th of a
second, this number usually does not need to be anywhere near the number of actual users, or the
number of statefully tracked connections. If there are no configured pipes, no pipe users will be
allocated, regardless of this setting. For more information about pipes and pipe users, see
Section 10.1, "Traffic Shaping".
Default: 512
