Auto discover NAT IP address
Selecting this option activates
ViaVideo’s automatic external IP
address feature, which discovers your
NAT’s external IP address and
automatically enters it in the NAT
outside (WAN) address field.
NAT outside (WAN) address
Specifies the external IP address used
by your NAT. If ViaVideo is unable to
discover your external IP address
automatically, you can enter it here.
IP Precedence Specifies the priority given IP packages
sent by ViaVideo. The default value for
IP precedence is 5.
Dynamic Bandwidth Specifies use of dynamic bandwidth
allocation. ViaVideo’s dynamic
bandwidth function automatically finds
the optimum line speed for a call.
If you experience excessive packet loss
while in a call, the dynamic bandwidth
function incrementally lowers the line
speed until there is no more packet loss.
After some time with no packet loss, the
dynamic bandwidth function
incrementally increases line speed until
packet loss occurs. At this point, the
dynamic bandwidth function lowers the
line speed one increment to ensure
minimal packet loss with maximum
throughput.
For more information about configuring your ViaVideo for operation
behind a firewall or NAT, see “Network Connection,” on page 63.
