Prestige 792H G.SHDSL Router 

 

NAT  

6-3 

 

NAT supports five types of IP/port mapping. They are: 

1.  One to One: In One-to-One mode, the Prestige maps one local IP address to one global IP address. 

2.  Many to One: In Many-to-One mode, the Prestige maps multiple local IP addresses to one global IP 

address. This is equivalent to SUA (for instance, PAT, port address translation), ZyXEL’s Single User 
Account feature that previous ZyXEL routers supported (the SUA Only option in today’s routers).  

3.  Many to Many Overload: In Many-to-Many Overload mode, the Prestige maps the multiple local IP 

addresses to shared global IP addresses. 

4.  Many-to-Many No Overload: In Many-to-Many No Overload mode, the Prestige maps each local IP 

address to a unique global IP address.
