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 AP 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 or 8.8.8.8 for the Google DNS server. 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.
Hostname to send when requesting DHCP: Specifies the name of this device as seen by
the remote DHCP server.
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
