13.6.6. nat sessions
Syntax:
nat sessions <i/f> [all | summary]
Description:
The nat sessions command displays a list of currently active NAT sessions on the interface <i/f>. In this context,
a session is a pair of source IP addresses and port numbers (and corresponding new port number) that NAT regards as
one side of an active connection. For each TCP or UDP session active, the source and destination IP address and port
number, and the local port number and the age of the session, are printed.
The all option causes the sessions command to print out information on every session, including sessions, which
have timed out. Normally the sessions command only shows active sessions (those which have not timed out). The
summary command does not show detailed information on each session, but only prints out the total number of active,
timed out and available sessions.
Example:
> nat sessions ppp
Proto Age NAT port Private address/port Public address/port
TCP 34 1024 192.168.219.38/3562 194.129.50.6/21
TCP 10 1025 192.168.219.64/2135 185.45.30.30/80
Total:
2 sessions active
101 sessions timed out
126 sessions available
