• Interface
Defines the interface (GPRS or Ethernet) to be used when establishing the L2TP-VPN
tunnel. In this example, the GPRS will be used.
• Primary server IP
The public IP address of the M2M Gateway, where the Arctic connects to.
This is the IP address obtained from Internet service provider.
• Primary server port
The UDP port, where the Arctic will connect to when establishing the L2TP-VPN
connection (port where M2M Gateway listens to incoming L2TP connections). The
default is port 1701, but it can be changed from M2M GW’s L2TP-VPN configuration.
Use the default port 1701 in this example.
• Primary server GW

example.
