14 Tunneling

￿SSL

￿UDP (available only in Connect Mode because it is a connectionless protocol).

￿AES encryption over UDP

￿Telnet

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.

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.

Note: The Local Port in Connect Mode is not the same port configured in Accept Mode.

To ignore data sent to the XPort Pro, enable the blocking of serial data or network data (or both).

The TCP keepalive time is the time in which probes are periodically sent to the other end of the connection. This ensures the other side is still connected.

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.

Connect Mode supports up to sixteen Hosts.

￿At least one Host is required to enable Connect Mode. The Host field contains all the information necessary to connect to that host.

Connect Mode has six states:

￿Disabled (no connection)

￿Enabled (always makes a connection)

￿Active if it sees any character from the serial port

￿Active if it sees a specific (configurable) character from the serial port

￿Modem control signal

￿Modem emulation

For the “any character” or “specific character” con nection states, 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 any character or the start character again (depending on the configured setting).

Configure the Modem Control Asserted setting (for DSR or DTR) to start a Connect Mode connection when the signal is asserted. The XPort Pro will try to make a connection indefinitely. If the connection closes, it will not make another connection unless the signal is asserted again.
