 AlwaysOn:
automatically establishes a connection. If the
network is disconnected because of external
factors when you are using the Internet access
service, the system tries connection every certain
time (for example, 10 seconds) until the connection
is established. If you pay for Internet access in the
monthly fee mode, you are recommended to use
this connection mode.
 OnDemand:
automatically establishes a connection when a
network access request from the LAN is received. If
no network access request is sent from the LAN
within the set time of Idle Timeout, the system
automatically interrupts the connection. If you pay
for Internet access by time, you are recommended
to use this connection mode, which effectively
saves the expense of Internet access.

dialup connection after startup.
You can keep it as default.
If this function is disabled, the modem obtains an IP
address assigned by an uplink equipment such as
BAS, through PPPoE dial-up. If this function is
enabled, the modem uses this IP address as the WAN
IP address.
NAT is one where all requests from the same internal
IP address and port are mapped to the same external
IP address and port. Furthermore, any external host
can send a packet to the internal host, by sending a
packet to the mapped external address.
