1.6.3 Exporting NAT Logs

NAT logs can be exported in two directions, either to the information center or to the
NAT log server.
In the former case, NAT logs are first converted into system logs and exported to the
local device's information center. Depending on the configuration of the information
system, NAT logs are again exported to their final destination. At most 10 NAT logs can
be exported to the information center at one time.
In the latter case, NAT logs are encapsulated into UDP packets and sent to the log
server, as shown in
with different packet formats. Only version 1 is used presently. A UDP packet is
composed of a header and several NAT logs.
