Chapter 11 Network Address Translation (NAT) The following table describes the fields in this screen. Table 62 Network Setting > NAT > Address Mapping LABEL DESCRIPTION Add New Rule Rule Name Local Start IP Local End IP Global Start IP Global End IP Type 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-toOne 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 (for example, PAT, port address translation), the Zyxel Device's Single User Account feature that previous routers supported only. Wan Interface Name Modify 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. 11.6.1 Add/Edit Address Mapping Rule To add or edit an address mapping rule, click Add new rule or the rule's edit icon in the Address Mapping screen to display the screen shown next. Specify the NAT mapping type, the local and global IP address(es), and a WAN interface in this screen. PX7511-B0 User's Guide 176

11.6.1
Add/Edit Address Mapping Rule
To add or edit an address mapping rule, click

Table 62
Network Setting > NAT > Address Mapping
LABEL
DESCRIPTION
Add New Rule
Click this to create a new rule.
Rule Name
This is the name of the rule.
Local Start IP
This is the starting Inside Local IP Address (ILA).
Local End IP
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.
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 the
Many-to-One
mapping type.
Global End IP
This is the ending Inside Global IP Address (IGA). This field is blank for
One-to-One
and
Many-to-
One
mapping types.
Type
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 (for example, PAT, port address translation), the Zyxel Device'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.
Wan Interface
Name
This is the WAN interface to which the address mapping rule applies.
Modify
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.
