Here, you can configure the LAN interfaces.
Predictable Network Interface Names (PNINs)
As of IGEL OS 11.06, the names of Ethernet and WLAN interfaces are predictable network interface names (PNINs), see Predictable Network Interface Names. This ensures the stability of interface names on reboot and generally improves the reliability of associating configurations with interfaces.
- As "
eth1", and "
wlan0" have been replaced by PNINs, configurations or custom scripts that include the old names of Ethernet and WLAN interfaces, e.g.
wlan0, have to be adjusted.
The following already existing configurations do NOT require manual adjustment since old names
eth1, etc. will internally be replaced by the correct PNINs automatically:
- To view the PNINs and the order of the configured interfaces, you can use the following commands. The default interface is always listed first, the second interface is listed second, etc.
cat /config/net/wl-interfaces(Note: Only the first wireless interface (former
wlan0) is supported. All other wireless interfaces will be ignored.)
- If you need to configure more than two Ethernet interfaces, go to System > Registry > network.interfaces.ethernet.device% and add an instance.
To explicitly assign a configuration instance to a certain interface, enter the corresponding PNIN for the registry key network.interfaces.ethernet.device%.ifname.
Activate default interface (Ethernet)
☑ The default interface is enabled. (Default)
☐ The Ethernet interface is not enabled.
Get IP from the DHCP server: The IP address of the client will be obtained automatically using DHCP. (Default)
DHCP options can be specified under DHCP Client.
Specify an IP address: The IP address and the network mask are entered manually.
IP address: IP address of the device.
Network mask: Network mask of the device.
Default gateway: IP address of the default gateway.
☑ Routing via the default gateway is enabled.
☐ Routing via the default gateway is not enabled. (Default)
Terminal name: Local name of the device. If the field is empty, the default name combined of '
ITC' with a MAC address will be generated.
☑ The manual DNS configuration will be used.
☐ The DNS configuration will be carried out by DHCP or BOOTP. (Default)
Default domain: Usually the name of the local network.
Name server: IP address of the name server to be used.
Name server: IP address of an alternative name server.
Manually overwrite DHCP settings
☑ The default route, the domain name, and the DNS server will be overwritten by manual entries.
☐ Manual entries will not overwrite DHCP settings. (Default)
Dynamic DNS registration:
☑ The terminal name will be registered dynamically via the DNS or DHCP server.
☐ The terminal name will not be registered dynamically. (Default)
Dynamic DNS registration method
- DHCP: Updates the terminal name through DHCP option 81.
- DNS: Sends updates to the DNS server in accordance with RFC 2136.
TSIG key file for additional DNS authentication: Path to the private key if TSIG-based DDNS registration is used.
