8.5 Configuring Address Mapping

Ordering your rules is important because the ZyXEL device applies the rules in the order that
you specify. When a rule matches the current packet, the ZyXEL device 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 ZyXEL device's Address Mapping settings, click SUA/NAT, then the
Address Mapping tab. The screen appears as shown.

DESCRIPTION
In addition to the servers for specified services, NAT supports a default server. A
default server receives packets from ports that are not specified in this screen.
If you do not assign a Default Server IP Address, the ZyXEL device discards all
packets received for ports that are not specified in this screen or remote
management.
