NAT changes the addressing of packets. A NAT rule tells
the EdgeRouter what action to take with a specific packet.
Define the following:
• Criteria for matching packets

Rules are organized into a set and applied in the specified
Rule Order. If the packets match a rule’s criteria, then its
action is performed. If not, then the next rule is applied.

Source NAT changes the source address of packets;
a typical scenario is that a private source needs to
communicate with a public destination. A Source NAT Rule
goes from the private network to the public network and
is applied after routing.
Add Source NAT Rule To create a new rule, click Add
Source NAT Rule. Go to “Add or Configure a Source NAT
Rule” on page 25.
