Network settings
•
Protocol
– select protocol assigning address to VoIP service interface:
•
Static
– operation mode where IP address and all the necessary settings for LAN interface are
assigned manually. When 'Static' type is selected, the following parameters will be available for
editing.
•
DHCP
– operation mode where IP address, subnet mask, DNS address and other necessary
settings for service operation (e.g. SIP and registration server static routes) are automatically
obtained from DHCP server.
Static
When 'Static' type is selected, the following parameters will be available for editing:
•
IP Address –
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]
•
Vendor
ID
(
Option 60
) – o
ption 60 value (Vendor class ID) 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 Appendix
DHCP client configuration in multiservice mode
.
IPsec settings
In this section you may configure IPSec encryption (IP Security). IPSec is a set of protocols used for protection
of data transmitted via Internet Protocol that enables authentication, integrity check and/or encryption of IP
packets. IPSec also includes secure Internet Key Exchange protocols.
In the current firmware version you may only access the device management interfaces (Web and Telnet)
using IPSec.
