Chapter 11 Network Address Translation (NAT) The following table describes the fields in this screen. Table 63 Address Mapping: Add/Edit LABEL Type DESCRIPTION Choose the IP/port mapping type from one of the following. 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. Local Start IP Local End IP Global Start IP Global End IP Set WAN Interface OK Cancel Many-to-Many: This mode maps multiple local IP addresses to shared global IP addresses. Enter the starting Inside Local IP Address (ILA). Enter 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. Enter 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. Enter the ending Inside Global IP Address (IGA). This field is blank for One-to-One and Many-to-One mapping types. Select the number of the mapping set for which you want to configure. Select a WAN interface to which the address mapping rule applies. Click OK to save your changes.

Click Network Setting > NAT > Sessions to display the following screen. Figure 86 Network Setting > NAT > Sessions The following table describes the fields in this screen. Table 64 Network Setting > NAT > Sessions LABEL DESCRIPTION MAX 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.
