Setup

Default Server

In addition to the servers for specified services, NAT supports a default server. A 

default server receives packets from ports that are not specified in this screen. If 

you do not assign a Default Server IP address, the ZyXEL Device discards all 

packets received for ports that are not specified here or in the remote management 

setup.
