Static NAT

Static NAT is the one-to-one mapping of an IP address on your private network to

an IP address from outside your network. Inbound rules must have external IP

addresses mapped to specific internal IP addresses.

Dynamic NAT

Dynamic NAT is the mapping, between a private network and the outside network,

of one address to a pool of addresses, a pool of addresses to one address or a pool

of addresses to another. The mappings are made in a translation table and remain

there until the table is cleared or until an entry times out.

To view Summary NAT screen:

1. On the navigation tree click Services, then click on the NAT heading.

The NAT Summary screen appears. The Summary screen attributes are:

2. Select the status of NAT, Disabled or Enabled.

3. Press Tab to save the setting.

Configuring an Interface with NAT

1. Choose NAT to expand the navigation tree and click on the interface you

want to configure. For example, LAN1.

The Rule Configuration and Rule Setting screens appear.

Note: Rules can be configured in one of two ways, using default rules or

setting up individual rules.

Adding Default rules

2. Select the status of Default Rules: Enabled or Disabled. The default is

Disabled. Two default rules are set. One is for TCP/UDP and the other for IP.

Both are outbound. The IP address for the Public address is the IP address of

the interface you configure. The system automatically fills in the rule order. If

you choose to add additional rules, the default rules still remain, unless you

disable Default Rules.

Note: Before you can specify the Rule Order you must first add the Rules.
