the Main Processor CPU. 
nat udp rev ip status zero
Indicates the number of times that an error in NAT translation for UDP reverse 
traffic has occurred.
nat udp rev usr index null
Indicates the number of times that a “port unreachable” message was

RTSP reply port not same
Indicates the number of times that the used port and proposed client port

Wrong port range
Indicates the number of times that the NAT port used a port in the wrong port 
range. For example, where a NAT port used a port from the normal port pool 
range for RTSP.
Port Pool Parameters
[x]
The variable represented by "x" represents the index of the IP address in the 
IP NAT pool. For example, [0] refers to the first IP address in the IP pool 
(216:220:209:230). [1] refers to the second IP address in this IP pool 
(216:220:209:231). 
h
The value following "h:" refers to the head of the port pool for the IP address 
in the IP NAT pool. The head indicates the location in the port pool where the 
next port will be allocated from.
t
The value following "t:" refers to the tail of the port pool for the IP address in 
the IP NAT pool. The tail indicates the location in the port pool where the next
