| Configuring Network Settings | 732. Configure and save the following settings:Parameter Description Configuration MethodWAN Port Link(WAN Port Link/PC Port Link)Specify the network speed andthe duplex mode for the system.Note: the default value is Auto.The network speed and duplexmode you select must besupported by the switch. WANPort Link and PC Port Link isonly applicable to VP59.If you change this parameter, thesystem will reboot to make thechange take effect.Web user interfaceRestricting Reserved PortsBy default, the system communicates through TCP and UDP ports from 50000 to 51000 for the video, thevoice, the presentation, and the camera control. The system uses only a small number of these ports duringa call. The specific number of the port depends on the number of participants in the call, the protocol used,and the number of ports required for the type of call (video or voice). To minimize the number of UDP andTCP ports that are available for communication, you can restrict the ports range.Procedure1. Do one of the following:• On your web user interface, go to Network > NAT/Firewall > Reserved Port.• On your VCS:On your VC880/VC800/VC500/PVT980/PVT950, go to More > Setting > Advanced > NAT/Firewall> Reserved Port.On your VC200, go to More > Network > Wired Network > NAT/Firewall > Reserved Port.On your VP59, tap Setting > Advanced > NAT/Firewall > Reserved Port.• On your CTP20, tap Setting > Advanced > NAT/Firewall > Reserved Port.2. Configure and save the following settings:Parameter Description Configuration MethodUDP Port Scope/UDP Lowest Port—UDPHighest PortConfigure the range of the UDPports.Note: the default UDP portrange is from 50000 to 51000.The valid value is from1024 to65000.SIP and H.323 calls share theconfigured ports.
