# Network Configuration
In the Administration → Network section you can:
# Network Diagnostics
TrueConf MCU is capable of performing network diagnostics using these commands: ping and traceroute. To do this, go to Administration → Network → Diagnostics.
# Using ping
You can check the availability of network resources using the ping command. To do this, enter the IP address or DNS - the name of the resource in the field with a text hint and press Validate. The check result will be displayed in the output field without the possibility of changing it.
If you enter an incorrect address in the input field, the output field will display an error from the server.
# Using traceroute
To determine the route of data packets in TCP/IP networks and the length of the path, you can use the traceroute command. To do this, follow the steps described in the previous section.
# Traffic capture
TrueConf MCU is also equipped with a network analysis tool. It allows recording all incoming and outgoing data packets and saving the data in the .pcap format for further analysis. To start data collection, select the required network interface from the drop-down list and press the Capture button. To "capture" traffic from all interfaces, select the Capture all option. During traffic recording, a table will appear below displaying a list of files, collection time, and their size.
Click the 
button to save the file to your device, or the 
button to delete it from the server.
# TCP/IP ports
# Port Range Configuration
To set up the parameters for transmitting audio and video streams, go to Administration → Network → TCP/IP ports. You can configure the port ranges for the following protocols:
BFCP
H.245
RTP.
# MTU and QoS
Here, you can also specify the size of RTP packets, or configure priorities for data stream transmission according to the DSCP (opens new window) protocol:
DSCP audio is for audio traffic
DSCP video is for video traffic
DSCP other is for other traffic, e.g. remote PTZ camera control.
The higher the number, the higher the priority of the selected type of transmitted packets.
# NAT Traversal
To configure NAT, navigate to Administration → Network → NAT traversal.
# Public IP address
If your server is behind NAT, you can define the public IPv4 address (WAN) here to be able to connect to the control panel from outside.
# Using ICE
When SIP clients are behind NAT or a firewall, problems usually arise when setting up direct connections for audio and video transmission. ICE solves this problem, enabling clients to discover available communication paths and choose the most efficient ones for setting up a connection.
To enable this protocol, activate the Use ICE switch.
# Using H.460.1
H.460.1 is a standard that enables the transfer of data (audio, video, etc.), providing a solution for establishing a direct connection between H.323 clients located behind NAT or a firewall.
H.460.18 defines the protocols and mechanisms for establishing direct media sessions through NAT devices, such as RTP and RTCP, allowing clients to exchange media data.
H.460.19 uses protocols such as HTTP and HTTPS to transfer data between clients, bypassing firewall restrictions. This allows clients to exchange information and establish connections, ensuring reliable and secure communication.
To use these features, activate the H.460.18 and H.460.19 checkboxes in Administration → Network → NAT traversal.
To use H.460.1, you need to enable gatekeeper registration in the server settings.
# TURN Settings
A TURN server performs the function of traffic relay between devices when a direct connection cannot be established due to NAT or other network restrictions. To pass through NAT using a TURN server, you need to specify: the hostname, login, and password.
# Network interfaces
Go to Administration → Network → Network interfaces to view the system name, MAC address of the network card (interface), or to set the IP addressing mode (static or DHCP). If static mode is selected, you also need to set:
IP address
Subnet mask
Gateway
Primary DNS server
Secondary DNS server.
