Chapter 11 Network Address Translation (NAT)
DESCRIPTION
Click this to create a new rule.
This is the name of the rule.
This is the starting Inside Local IP Address (ILA).
This is the ending Inside Local IP Address (ILA). If the rule is for all local IP addresses, then
this field displays 0.0.0.0 as the Local Start IP address and 255.255.255.255 as the Local
End IP address. 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.
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: This mode maps multiple local IP addresses to one global IP address. This is
equivalent to SUA (i.e., PAT, port address translation), the VMG'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 is the WAN interface to which the address mapping rule applies.
Click the Edit icon to go to the screen where you can edit the address mapping rule.
Click the Delete icon to delete an existing address mapping rule. Note that subsequent
address mapping rules move up by one when you take this action.
