can access the Internet directly, the NAT function can be disabled.

automatically re-establish the PPP session when disconnected by the ISP.
Connect on Demand: If you want to establish a PPP session only when there is a packet
requesting access to the Internet (i.e. when a program on your computer attempts to access the
Internet).
Idle Timeout: Auto-disconnect the broadband firewall gateway when there is no activity on the line for a
predetermined period of time.
