Chapter 10 Network Address Translation (NAT) Table 67 Network Setting > NAT > Address Mapping (continued) LABEL Global Start IP Global End IP Type DESCRIPTION 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 Device's Single User Account feature that previous routers supported only. Modify Many-to-Many: This mode maps multiple local IP addresses to shared global IP addresses. 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. 10.9 The Sessions Screen Use this screen to limit the number of concurrent NAT sessions a client can use. Click Network Setting > NAT > Sessions to display the following screen. Figure 95 Network Setting > NAT > Sessions The following table describes the fields in this screen. Table 68 Network Setting > NAT > Sessions LABEL DESCRIPTION WAX NAT Session Per Host Use this field to set a limit to the number of concurrent NAT sessions each client host can have. If only a few clients use peer to peer applications, you can raise this number to improve their performance. With heavy peer-to-peer application use, lower this number to ensure no single client uses too many of the available NAT sessions. Apply Click this to save your changes on this screen. Cancel Click this to exit this screen without saving any changes. 10.10 Technical Reference This part contains more information regarding NAT. VMG8324-B10A / VMG8324-B30A Series User's Guide 169
