To create a new NAT rule:
1. If the NAT rules table is not shown on the page, click the View NAT rules link.
2. Click the arrow next to New.
3. Click one of the available positioning options for the rule: Top Rule, Bottom Rule, Above
Selected, or Under Selected.
The Add Manual NAT Rule window opens. It shows the rule fields in two manners:
n
A rule summary sentence with default values.
n
A table with the Rule Base fields in a table.
4. Click the links in the rule summary or the table cells to select network objects or options
that fill out the Rule Base fields. See the descriptions above.
5. In the Write a comment field, enter optional text that describes the rule. This is shown as
a comment below the rule in NAT Manual Rules.
6. Select the Hide multiple sources behind the translated source addresses if you want
the original source to contain multiple IP addresses, IP ranges, networks, etc. and the
translated source to be a single IP address.
When this option is not selected, you can still use an IP range in the Original Source and
a different IP range of the same size in the Translated Source. This rule does the IP
address translation from one range to another, respectively (the first IP in the first range
is translated to the first IP in the second range, and so on).
7. Select Serve as an ARP Proxy for the original destination's IP address for the gateway
to reply to ARP requests sent to the original destination's IP address. Note that this does
not apply to IP ranges or networks.
8. Click Apply
After you create manual rule, it is added to the NAT rules table under the Manual NAT Rules
section.
To edit a rule:
Note - For Access Policy rules, you can only edit the tracking options for automatically
generated rules.
1. Select a rule and click Edit.
2. Edit the fields as necessary.
3. Click Apply
