Prestige 861H Series User's Guide 6.6 Configuring Address Mapping Ordering your rules is important because the Prestige applies the rules in the order that you specify. When a rule matches the current packet, the Prestige 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 Prestige's address mapping settings, click NAT, Select Full Feature and click Edit Details to open the following screen. Figure 33 Address Mapping Rules The following table describes the fields in this screen. Table 20 Address Mapping Rules LABEL Local Start IP Local End IP Global Start IP Global End IP DESCRIPTION This is the starting Inside Local IP Address (ILA).
