11 • NAT/NAPT configuration
Mode:
profile napt <pf-name>
Preserving TCP/UDP port numbers in NAPT
The NAPT can be configured to preserve the TCP/UDP port number of outbound packets sent from local
hosts towards the global NAPT interface. If this option is enabled the NAPT tries not to change these port
numbers. If the port is however already in use, the NAPT will ignore this setting and assign a port number
from the configured TCP/UDP port ranges.
Mode:
profile napt <pf-name>
Defining the UDP NAPT type
The NAPT type to be applied for UDP packets is configurable using the following procedure. The NAPT sup-
ports the UDP translation types shown in the following list. The list is ordered by the security of the NAPT
type starting with the highest security type.
•
symmetric
•
port-restricted-cone
•
address-restricted-cone
•
full-cone
You find a detailed description of these NAPT types in section 5 of RFC3489. To allow STUN to work
through the NAPT the
full-cone setting
is usually required. The default setting is
symmetric
.
