DHCP Connection Settings
Routing Mode
NAT allows substituting the real address in a packet with a mapped address
that is routable on the destination network. By clicking the help icon in this
field, you can display the IP Forwarding option, if your network requires it.
Hostname
(Optional)
If your service provider's DHCP server requires you to supply a hostname
value upon acquiring an IP address, you may enter the value here. If your
service provider does not provide you with the value, you can safely bypass
this option.
Management IP
Address
Management IP Address is available for configuration when you click the
link in the help icon via the Hostname.
This option allows you to configure the management IP address for the
DHCP WAN connection.
DNS Servers
Each ISP may provide a set of DNS servers for DNS lookups. This setting
specifies the DNS (Domain Name System) servers to be used when a DNS
lookup is routed through this connection.
Selecting Obtain DNS server address automatically results in the DNS
servers being assigned by the WAN DHCP server to be used for outbound
DNS lookups over the connection. (The DNS servers are obtained along with
the WAN IP address assigned from the DHCP server.)
When Use the following DNS server address(es) is selected, you may
enter custom DNS server addresses for this WAN connection into the DNS
Server 1 and DNS Server 2 fields.
IP Passthrough
When this IP Passthrough option is active, after the ethernet WAN
connection is up, the router's DHCP server will offer the connection's IP
address to one LAN client. All incoming or outgoing traffic will be routed
without NAT.
Regardless the WAN connection's state, the router always binds to the LAN
IP address (Default: 192.168.50.1). So when the ethernet WAN is connected,
the LAN client could access the router's web admin by manually configuring
its IP address to the same subnet as the router's LAN IP address (e.g.
192.168.50.10).
Note: when this option is firstly enabled, the LAN client may not be able to
refresh its IP address to the ethernet WAN IP address in a timely fashion.
The LAN client may have to manually renew its IP address from DHCP
server. After this option is enabled, the DHCP lease time will be 2 minutes.
I.e. the LAN client could refresh its IP address and access the network at
most one minute after the ethernet WAN connection goes up.
Independent from
Backup WANs
If this is checked, the connection will be working independent from other
Backup WAN connections. Those in Backup Priority will ignore the status of
