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.
Many-to-Many
: This mode maps multiple local IP addresses to shared global IP addresses.
