This option is typically used for DSL services. Some DSL service providers supply a special
DSL modem. This kind of modem only supports the PPTP tunnel to access the Internet, you
should create a PPTP tunnel that carries a PPP session and terminates on the DSL model.
Once the tunnel has been established, this kind of DSL modem will forward the PPP session
to the ISP. As long as the PPP session is connected, all the local users will be able to share
this PPP session to access to the Internet.
Apply 3G or 3.5G transmission rate for the backup. Once Dynamic IP connection is
disconnected, the system automatically connects Internet via 3.5G adapter. If 3.5G signal is
not available, it starts to search downward for 3/2.75/2.5G signals until none existed.
Setting up the interval time to auto detect whether the Internet connection is lost or not. If yes,
the system immediately switches to 3.5G Internet connection and will disconnect
automatically the original PPTP connection recovers.
