
UDP Port: this is the UDP port to be used in the tunnel establishment, as follows:
o If the 9992-ENC is a Server , it will listen on this UDP port for incoming tunnel
connections.
o If the 9992-ENC is a Client , it will attempt to connect to this port in the server.

Tunnel Mode: The 9992-ENC can be either a Server or a Client . If it is a server, it will
wait to be contacted. If it is a client, it will actively attempt to contact the server. If
Client is selected, an additional field appears where the server IP address can be entered:

Interface: selects the network interface to use for this communication. The value of Any
allows the device to select the most convenient interface based on the IP address. In
particular, if the 9992-ENC is configured as a server, it will accept incoming connections
on both Ethernet ports if the interface is set to
Any .

Reduced Overhead: RIST Main Profile defines a Reduced Overhead mode where only a
simplified header. This reduces the overhead from 2.4% to 0.6%. This checkbox enables
the use of Reduced Overhead mode for transmitted packets. Note that the 9992-ENC
automatically detects incoming reduced overhead packets.

Remap UDP: This box, if checked, causes the 9992-ENC to assume that all UDP packets
coming in from the tunnel are destined to it regardless of their destination address. This
control disappears in Reduced Overhead mode.

Encryption: If this box is checked, the tunnel will be encrypted using DTLS, with
optional authentication. Checking this box requires the +RIST/ENCRP-ENC license.
Once this box is checked, the following additional options become available:
o Authentication: If this box is not checked, the 9992-ENC will accept encrypted
connections from any other device (regardless of whether it is operating as a
client or a server). If it is checked, only authenticated connections will be
accepted. Note that authentication requires prior setup to define acceptable
connections; simply checking this box without any preparation will cause all
connections (both incoming and outgoing) to fail. For a detailed explanation of
how to set up the authentication function, please consult the section entitled
“RIST Main Profile Authentication” later in this manual.
o Allowed Ciphers: When the 9992-ENC negotiates an encrypted channel with a
remote peer, it will negotiate a cipher suite, which includes both encryption and
