17: Tunnel Connecting Multiple Hosts The Connect mode supports up to 4 hosts. Hosts may be accessed sequentially or simultaneously.  Sequential - A tunnel will connect to hosts in sequential order. The host specified as Host 1 will be attempted first. If that fails, it will proceed to Host 2, 3, and 4. When a connection drops, the cycle starts again with Host 1 and proceeds in order. Sequential is the default Host mode.  Simultaneous - A tunnel will connect to all hosts accepting a connection. Simultaneous connections occur at the same time to all listed hosts. The gateway can support a maximum of 4 connections. Tunnel Disconnect Disconnect specifies the optional conditions for disconnecting any tunnel connection that may be established. If any of these conditions are selected but do not occur and the network disconnects the tunnel, a Connect mode connection will attempt to reconnect. However, if none of these conditions are selected, a closure from the network is taken as a disconnected host. To configure Disconnect settings: 1. Go to Tunnel > Tunnel 1, Tunnel 2, Tunnel SPP Slave, or Tunnel SPP Master. 2. Under Disconnect, enter the configuration settings. 3. Click Save & Apply.

G520 Series IoT Cellular Gateway User Guide

Connecting Multiple Hosts
The Connect mode supports up to 4 hosts. Hosts may be accessed sequentially or
simultaneously.
Sequential
– A tunnel will connect to hosts in sequential order. The host specified as Host 1
will be attempted first. If that fails, it will proceed to Host 2, 3, and 4. When a connection drops,
the cycle starts again with Host 1 and proceeds in order. Sequential is the default Host mode.
Simultaneous
– A tunnel will connect to all hosts accepting a connection. Simultaneous
connections occur at the same time to all listed hosts. The gateway can support a maximum of
4 connections.
Tunnel Disconnect
Disconnect specifies the optional conditions for disconnecting any tunnel connection that may be
established. If any of these conditions are selected but do not occur and the network disconnects
the tunnel, a Connect mode connection will attempt to reconnect. However, if none of these
conditions are selected, a closure from the network is taken as a disconnected host.
To configure Disconnect settings:
1.
Go to Tunnel > Tunnel 1, Tunnel 2, Tunnel SPP Slave, or Tunnel SPP Master.
2.
Under Disconnect, enter the configuration settings.
3.
Click
Save & Apply
