Table 109 Menu 15.1.1: Address Mapping Rules - ZyXEL Communications P-793H User Manual

Note: The Type, Local and Global Start/End IPs are configured in menu 15.1.1.1
(described later) and the values are displayed here.

Table 109 Menu 15.1.1: Address Mapping Rules

FIELD
Set Name
Idx
Local Start IP
Local End IP
Global Start IP This is the starting global IP address (IGA). If you have a dynamic IP, enter 0.0.0.0 as
Global End IP This is the ending global IP address (IGA).
Type
Once you have finished configuring a rule in this menu, press [ENTER] at the message "Press ENTER
to Confirm..." to save your configuration, or press [ESC] to cancel.
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 as old rule 5 becomes rule
4, old rule 6 becomes rule 5 and old rule 7 becomes rule 6.
Note: You must press [ENTER] at the bottom of the screen to save the whole set.
You must do this again if you make any changes to the set – including deleting
a rule. No changes to the set take place until this action is taken.
Selecting Edit in the Action field and then selecting a rule brings up the following menu,
Menu 15.1.1.1 - Address Mapping Rule in which you can edit an individual rule and
configure the Type, Local and Global Start/End IPs.
Note: An IP End address must be numerically greater than its corresponding IP Start
address.

This is the index or rule number.
Local Start IP is the starting local IP address (ILA).

start IP is 0.0.0.0 and the end IP is 255.255.255.255.

These are the mapping types discussed above. Server allows us to specify multiple
