System Information and Diagnostics

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.
