DESCRIPTION
Type
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 / Source NAT
: This mode maps multiple local IP addresses to one global IP address.
This is equivalent to SUA (that is, PAT, port address translation), the SBG'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.
