Tunnel – Connect Mode
Connect Mode defines how the device makes an outgoing connection. When enabled, Connect
Mode is always on and attempting a network connection if the connection mode condition warrants
it. For Connect Mode to function, it must:
Be enabled
Have a remote host configured
Have a remote port is configured
Enter the remote host address as an IP address or DNS name. The XPort Pro device will make a
connection only if it can resolve the address. For DNS names, the XPort Pro will re-evaluate the
address after being established for 4 hours. If re-evaluation results in a different address, it will
close the connection.
Connect Mode supports the following protocols:
TCP
AES encryption over TCP and UDP
When setting AES encryption, both the encrypt key and the decrypt key must be specified.
The encrypt key is used for data sent out. The decrypt key is used for receiving data. Both of
the keys may be set to the same value.
SSH
To configure SSH, the SSH client username must be configured. In Connect Mode, the XPort
Pro is the SSH client. Ensure the XPort Pro SSH client username is configured on the remote
SSH server before using it with the XPort Pro.
SSL
UDP
Is only available in Connect Mode because it is a connectionless protocol. For Connect Mode
using UDP, the XPort Pro accepts packets from any device on the network. It will send
packets to the last device that sent it packets.
Telnet
Note:
The Local Port in Connect Mode is independent of the port configured in Accept
Mode.
There are six different connect modes:
Disable
No connection is attempted.
Always
A connection is always attempted.
Any Character
A connection is attempted if it detects any
character from the serial port.
Start Character
A connection is attempted if it detects a specific and configurable character from the serial
port.
Note:
While in the “Any Character” or “Start
Character” connection modes, the XPort Pro
waits and retries the connection if the
connection cannot be made. Once it makes
a connection and then disconnects, it will
not reconnect until it sees another character
or the start character again (depending on
the configured setting).
