Scenario
Digi Connect family VPN router (for example ConnectPort WAN or Digi Connect WAN
IA) is used for remote site connectivity. Juniper Netscreen is used at the local site for
connectivity. The connection between the two networks needs to be secure for data
transmission.
Theory of Operation
A location needs to be able to build a secure tunnel between the main site and a remote
branch. One location has a Digi Connect router to provide primary internet connectivity.
The other location uses a Juniper Netscreen for primary internet connectivity. The Digi
Connect router will create a VPN tunnel to the Juniper Netscreen, creating a secure
connection.

Carrier Plan and VPN Appliance Requirements
Digi Connect Router Requirements: Firmware version must be 2.8 or later. To
download the latest firmware, go to http://www.digi.com/support.
GSM GPRS/EDGE APN Type needed: VPN and GRE end-points usually require static
(persistent) IP addresses and must support mobile terminated data connections. If mobile
termination is not an option with your current APN, you will need to acquire a new one
that does support mobile termination.
CDMA networks may also require special plans to provide static IP addresses and
support mobile terminated data connections.
Check with your wireless provider on the available plan types.
