9.4 Confi guring Address Mapping
Ordering your rules is important because the WR3000 Wireless Router applies the rules in the
order that you specify. When a rule matches the current packet, the WR3000 Wireless Router
takes the corresponding action and the remaining rules are ignored. If there are any empty rules
before your new confi gured rule, your confi gured rule will be pushed up by that number of empty
rules. For example, if you have already confi gured rules 1 to 6 in your current set and now you
confi gure 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 WR3000 Wireless Router’s address mapping settings, click
ADVANCED, SUA/
NAT
and then the
Address Mapping tab
. The screen appears as shown.
The table below describes the setting in the above screen.
