Description
Enter an authentication user name if PPPoE service is selected, and there is no default value.
Enter an authentication password if PPPoE service is selected, and there is no default value.
If "Static IP" or "DHCP" is selected but an address fails to be obtained, the gateways will use
the IP address filled in here. If the gateways obtain an IP address through DHCP, the system
will display the current IP address automatically obtained from DHCP.
The subnet mask is used with an IP address. When the gateway uses a static IP address, this
parameter must be entered; when an IP address is automatically obtained through DHCP, the
system will display the subnet mask automatically obtained by DHCP. It has no default value.
The IP address of LAN gateway. When the gateway obtains an IP address through DHCP, the
system will display the LAN gateway address automatically obtained through DHCP. It has no
default value.
Obtained automatically: When the connection mode is "DHCP" or "PPPoE", the device uses the
automatically obtained IP address of the DNS server.
Specified manually: Use the DNS server addresses specified manually.
If Specified manually is selected, the network IP address of the Primary DNS server must be
entered, there is no default value.
If Specified manually is selected, the network IP address of the Secondary DNS server can be
entered, there is no default value.
ETH2 configurations
 Switching port:
ETH1 and ETH2 are switch ports. The two ports share the IP address
of ETH1 on the Web GUI.
 Redundant port for ETH1:
this mode, both ETH1 and ETH2 are connected to the same LAN or WAN, if ETH1
is damaged or offline, ETH2 automatically connects the network.
The device periodically sends a STUN request to the STUN server to obtain the public IP
address for the front-end router.
It is disabled by default.
Set the IP address or domain name of the STUN server. The factory default STUN server is the
STUN server.
Set the port of STUN server. It is 3478 by default.
The interval at which the device sends a STUN request ranges from 30 to 3600 seconds. It is 60
second by default.
Trunk re-registration: A re-registration of the SIP trunk is triggered upon the detection of

the change of the public IP address of the device by using STUN query. Normally, the session
interval of STUN request should be shorter than the registration period.
Note: The IP address obtained through STUN is used only for re-registration of SIP server,
and it is not used in SIP message fields such as Via and Contact and SDP C field.
Trunk re-registration & NAT address updating: A re-registration of the SIP trunk is

triggered upon the detection of the change of the public IP address of the device by using
STUN query. The IP address obtained through STUN is used in SIP message fields such as
Via and Contact and SDP C field.
