6.6 Configuring Address Mapping
Ordering your rules is important because the TELKOM ADSL 5100 applies the rules in the order
that you specify. When a rule matches the current packet, the TELKOM ADSL 5100 takes the
corresponding action and the remaining rules are ignored. If there are any empty rules before
your new configured rule, your configured rule will be pushed up by that number of empty rules.
For example, if you have already configured rules 1 to 6 in your current set and now you configure
rule number 9. In the set summary screen, the new rule will be rule 7, not 9. Now if you delete rule
4, rules 5 to 7 will be pushed up by 1 rule, so old rules 5, 6 and 7 become new rules 4, 5 and 6.
To change your TELKOM ADSL 5100’s address mapping settings, click NAT, Select Full Feature
and click Edit Details to open the following screen.
The following table describes the labels in this screen.
