Chapter 11 Network Address Translation (NAT) Table 61 Network Setting > NAT > Address Mapping (continued) LABEL DESCRIPTION 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 (i.e., PAT, port address translation), the VMG's Single User Account feature that previous routers supported only. WAN Interface 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. 11.7.1 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.
