Choose the port mapping type from one of the following. 1. One-to-One: One-to-one mode maps one local IP address to one global IP address. Note that port numbers do not change for One-toone NAT mapping type. 2. Many-to-One: Many-to-One mode maps multiple local IP addresses to one global IP address. This is equivalent to SUA (in other words, PAT, or port address translation), ZyXEL's Single User Account feature. 3. Many-to-Many Ov (Overload): Many-to-Many Overload mode maps multiple local IP addresses to shared global IP addresses. 4. Many One-to-One: Many One-to-one mode maps each local IP address to unique global IP addresses. Local Start IP Local End IP 5. Server: This type allows you to specify inside servers of different services behind the NAT to be accessible to the outside world. This is the starting Inside Local IP Address (ILA). Local IP addresses are N/A for Server port mapping. This is the end Inside Local IP Address (ILA). If your rule is for all local IP addresses, then enter 0.0.0.0 as the Local Start IP address and 255.255.255.255 as the Local End IP address. Global Start IP This field is N/A for One-to-One and Server 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.
