Chapter 8 Network Address Translation (NAT)
DESCRIPTION
Click this to create a new address mapping rule.
Double-click an address mapping rule or select it and click Edit to open a screen where you can
modify the rule's settings.
To remove an existing address mapping rule, select it and click Remove.
This is the index number of the rule.
This is the address mapping type.
One-to-One: This 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.
Many-to-One / Source NAT: This mode maps multiple local IP addresses to one global IP address.
This is equivalent to SUA (that is, PAT, port address translation), the SBG's Single User Account
feature that previous routers supported only.
Many-to-Many: This mode maps multiple local IP addresses to shared global IP addresses.
This shows the WAN interface through which the address mapping is forwarded.
This is the starting Inside Local IP Address (ILA).
This is the ending Inside Local IP Address (ILA). This field is blank for One-to-One mapping types.
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 the Many-to-One mapping type.
This is the ending Inside Global IP Address (IGA). This field is blank for One-to-One and Many-to-
One mapping types.
