Configuring Dynamic NAT
NOTE The invert option in this example filter makes this specific configuration easier but
is not a requirement for dynamic NAT.
NOTE Dynamic NAT solutions apply only to TCP/UDP traffic. Also, filters for dynamic
NAT should be given a higher numbers than any static NAT filters (see Static NAT on page
191).
