or Static address, where you can specify the device IP
address. Other protocols are PPTP, PPPoE, and L2TP.
Protocol – Static address
IPv4 address: Sets the IP address of the device as
seen from the WAN zone.
IPv4 netmask: Sets the subnet mask e.g.
255.255.255.0. The IP address and netmask together
determine the subnet or network ID e.g.
192.168.3.0/24. Two devices must be in the same
subnet in order to establish a (Layer 2) link between
them.
IPv4 gateway: Specifies the IP address of the remote
server that allows the device's shell to gain internet
access.
IPv4 broadcast: Specifies the IPv4 broadcast address,
optional.
Use custom DNS servers: Configures the IP address of
the DNS servers e.g. 165.21.100.88 for the SingNet
DNS server in Singapore or 8.8.8.8 for the Google DNS
server in the USA. The computers in the same subnet
as this device can then set this device's IP address as
their preferred DNS server to obtain the same DNS
service.
Protocol – DHCP client
The Dynamic Host Configuration Protocol (DHCP) is a
standardized networking protocol used by servers on
an IP network to allocate IP addresses automatically
to client devices.
Hostname to send when requesting DHCP: Specifies
the name of this device as seen by the remote DHCP
server.
Protocol – PPTP
The Point-to-Point Tunneling Protocol (PPTP) is a
method for implementing virtual private networks.
PPTP uses a control channel over Transmission
Control Protocol (TCP) and a Generic Routing
Encapsulation (GRE) tunnel operating to encapsulate
Point-to-Point Protocol (PPP) packets.
VPN Server: Specifies the IP address of the remote
PPTP server for the virtual private network (VPN).
PAP/CHAP username: Sets the username for the
Password Authentication Protocol (PAP) or the
Challenge-Handshake Authentication Protocol (CHAP).
PAP/CHAP password: Sets the password for the PAP
or CHAP.
Configure PPTP IP settings: Upon clicking the
“Configure...” button, the PPTP Common
Configuration page would be displayed. The protocol
DHCP client or Static address can be selected. The
corresponding options are explained within this
section (5.1.1 Common Configuration).
Protocol – PPPoE
The Point-to-Point Protocol over Ethernet (PPPoE) is a
network protocol for encapsulating PPP frames inside
Ethernet frames. Most DSL providers use PPPoE,
which provides authentication, encryption, and
compression.
The options PAP/CHAP username and PAP/CHAP
password have been explained earlier.
Access Concentrator: Identifies the PPPoE server.
Leave empty to autodetect.
Service Name: Specifies the PPPoE service name. The
server will accept clients which send an initialization
message with the service name that matches the
server's configuration. Leave empty to autodetect.
Protocol – L2TP
The Layer 2 Tunneling Protocol (L2TP) is a tunneling
protocol used to support virtual private networks
(VPNs) or as part of the delivery of services by ISPs. It
does not provide any encryption or confidentiality by
itself. Rather, it relies on an encryption protocol that it
passes within the tunnel to provide privacy.
The options PAP/CHAP username and PAP/CHAP
password have been explained earlier.
