Usage Guidelines

After Smart 3-Tuple NAT is configured, the port assignment mode can be determined based on destination port numbers. If a packet's destination port number is in the configured range, the NAPT mode is used for port assignment; otherwise, the 3-Tuple NAT mode is used.

By default, Smart 3-Tuple NAT is not configured.

Only the USG6510E/6510E-POE/6530E does not support this command.

Example

# Configure Smart 3-Tuple NAT so that NAPT is performed for packets whose destination ports are in the range from 1000 to 2000.
