CROSSLOCK VPN
UDP Port - Sets the UDP port used for Crosslock VPN Connections. Default is set to UDP 9001.
Permissive - Allows users to accept Crosslock connections from any unit. This is set to No by default.
Authentication - Enables the authentication of connections. Default setting is No.
Protection - Enables AES encryption and payload integrity protection to prevent tampering with or interception of
the transmitted content. This option has a SIGNIFICANT system overhead. Default setting is No.
Maximum Delay - Maximum allowed target delay, in milliseconds. Set to 5000 ms by default.
FEC - Enables data loss protection. This option controls protection on data transmitted to the remote end. Disabled
by default.
FEC Delay - Amount of delay to allow for FEC. Lower packet rates will require higher delay to remain effective.
Rentransmit - Enables retransmission of lost data. This option controls protection on data transmitted to the remote
end.
Header Compression - Enables the compression of headers to reduce overhead, especially at lower bitrates. Default
is set to Yes.
Base FEC - Applies a constant base amount of FEC sufficient to recover the specified rate of packet loss. Default is set
to 0%.
STUN Server - Displays IP address of the STUN Server. Default is stun.comrex.com.
Always Connect - Allows users to attempt to maintain a VPN connection to a selected peer whenever possible.
Default is set to None.
BRIC NORMAL SETTINGS
IP Port - This option defines the incoming UDP port—the number to be used for incoming IP connections. The
default is UDP 9000. Crosslock connection is defaulted to UDP 9001. Note that since most BRIC-Link codecs attempt
a connection on this port number, changing it can mean the remote units in the field must dial specifically to the
new port number in order to connect to the BRIC-Link. An outgoing call must be made to a specific port number
in the form of IP-ADDRESS:PORT#. For example, dialing port UDP 5004 on the Comrex test line is formatted
70.22.155.131:5004.
