Ordering your rules is important because the ADSL Router applies the rules in the
order that you specify. When a rule matches the current packet, the ADSL Router
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 the ADSL Router’s address mapping settings.
The following table describes the labels in this screen.
Label Description
Rule Index Chose the number
Rule Type 1-1: One-to-one mode maps one local IP address to one
global IP address. Note that port numbers do not change for
the One-to-one NAT mapping type.
M-1: Many-to-One mode maps multiple local IP addresses to
one global IP address.
M-M Ov (Overload): Many-to-Many Overload mode maps
multiple local IP addresses to shared global IP addresses.
MM No (No Overload): Many-to-Many No Overload mode
maps each local IP address to unique global IP addresses.
Server(available on next release of firmware): This type allows
you to specify inside servers of different services behind the
NAT to be accessible to the outside world.
Local Start IP This is the starting Inside Local IP Address (ILA). Local IP
addresses are N/A for Server port mapping.
Local End IP This is the end Inside Local IP Address (ILA). If your rule is for
all local IP addresses, then enter 0.0.0.0 as the Local Start IP
address and 255.255.255.255 as the Local End IP address.
This field is N/A for One-to-one and Server mapping types.
Public Start IP This is the starting Inside Global IP Address (IGA). Enter
0.0.0.0 here if you have a dynamic IP address from your ISP.
You can only do this for Many-to-One and Server mapping
types.
Public End IP This is the ending Inside Global IP Address (IGA). This field is
N/A for One-to-one, Many-to-One and Server mapping types.
