Configuring Address Mapping - Telkom ADSL 5100 Instruction Manual

6.6 Configuring Address Mapping

Ordering your rules is important because the TELKOM ADSL 5100 applies the rules in the order
that you specify. When a rule matches the current packet, the TELKOM ADSL 5100 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 TELKOM ADSL 5100's address mapping settings, click NAT, Select Full Feature
and click Edit Details to open the following screen.
The following table describes the labels in this screen.
LABEL
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.
Global 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.
Global 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.
