LAN
•Protocol– select the protocol that will be used for device LAN interface connection to provider network:
•Static– operation mode where IP address and all the necessary parameters for LAN interface are
assigned statically;
•DHCP– operation mode where IP address, subnet mask, DNS address, default gateway and other
necessary settings for network operation are automatically obtained from DHCP server.;
•PPPOE– operation mode when PPP session is established on LAN interface.
Static
When 'Static' type is selected, the following parameters will be available for editing:
•IPAddress – specify the device LAN interface IP address in the provider network;
•Netmask– external subnet mask;
•Default gateway– address that the packet will be sent to, when route for it is not found in the routing
table;
•1st DNS Server,2nd DNS Server– domain name server addresses (allow identifying the IP address of the
device by its domain name).You may leave these fields empty, if they are not required.
•MTU–maximum size of the data unit transmitted on the network.
DHCP
When 'DHCP' type is selected, the following parameters will be available for editing:
•Alternative Vendor ID (Option 60)–when selected, the device transmits Vendor ID (Option 60) field value
in Option 60 DHCP messages (Vendor class ID).If the field is empty, Option 60 will not be transmitted in
DHCP messages:
[VENDOR:device vendor][DEVICE:device type][HW:hardware version] [SN:serial number][WAN:WAN
interface MAC address][LAN:LAN interface MAC address][VERSION:firmware version]
Example:[VENDOR:Eltex][DEVICE:VP-12P][HW:1.0][SN:VI23000118] [WAN:A8:F9:4B:03:2A:D0][LAN:
02:20:80:a8:f9:4b][VERSION:#1.1.0]
•VendorID(Option 60) – option 60 value (VendorclassID) which is transmitted in DHCP messages.
When the field is empty, option 60 is not transmitted in DHCP messages.
•1st DNS Server,2nd DNS Server– domain name server addresses (allow identifying the IP address of the
device by its domain name. Addresses, which are specified statically, have the higher priority than
addresses obtained via DHCP.
•MTU– maximum size of the data unit transmitted on the network.
You can manually assign the List of used DHCP options on each network interface (Internet, VoIP, and
Management). See AppendixDHCP client configuration in multiservice mode.
PPPoE
When 'PPPoE' type is selected, the following parameters will be available for editing:
•User Name– username for authorization on PPP server.
•Password– password for authorization.
•MTU– maximum size of the data unit transmitted on the network(recommended value– 1492).
