• SNTP - Support for system time by SNTP (Simple Network Time Protocol).

• Dynamic DNS - Support for dynamic DNS services provided by dyndns.org

and no-ip.com, so that the SMCWHSG44-G can be associated with a domain

name even if it obtains an IP address dynamically by PPP, PPPoE or DHCP.

• LAN Device Management - The Wireless Hotspot Gateway can pass

management requests from the Internet through its built-in NAT server to

devices on the private network. As a result, network devices (such as

access points) behind the NAT server can be managed from the Internet.

In this way, the Wireless Hotspot Gateway acts as a management proxy for

the LAN devices.

• Firmware Tools

• Firmware upgrade - The firmware can be upgraded, so that more

features can be added in the future.

• TFTP-based - Upgrading firmware by TFTP (Trivial File Transfer Protocol).

• HTTP-based - Upgrading firmware by HTTP (Hyper Text Transfer Protocol).

• Configuration backup. The configuration settings of the SMCWHSG44-G

can be backed up to a file via TFTP or HTTP for restoring later.

• Management

• Web-based Network Manager for configuring and monitoring the

SMCWHSG44-G - The management protocol is HTTP (Hyper Text Transfer

Protocol)-based. The SMCWHSG44-G can be configured to be managed:

• Only from the LAN side

• Both from the LAN side and WAN side

• Only from the WAN side

In addition, it can also be configured to accept management commands only

from specific hosts.

• UPnP - The SMCWHSG44-G responds to UPnP discovery messages so

that a Windows XP user can locate the Wireless Hotspot Gateway in My

Network Places and use a Web browser to configure it.

• SNMP - SNMP (Simple Network Management Protocol) MIB I, MIB II,

IEEE 802.1d, IEEE 802.1x, Private Enterprise MIB are supported.

• System log - For system operational status monitoring.

• Local log - System events are logged to the on-board RAM of the

Gateway and can be viewed using a Web browser.

• Remote log by SNMP trap - Systems events are sent in the form of

SNMP traps to a remote SNMP management server.

• LAN/WAN Configurable Ethernet Switch Ports - The SMCWHSG44-G provides

a 4-port Ethernet switch so that a stand-alone Ethernet hub/switch is not

necessary for connecting Ethernet client computers to the Router. These

Ethernet ports can be configured as WAN ports for multiple DSL/cable-

based Internet connections support.

• Hardware Watchdog Timer - If the firmware gets stuck in an invalid state,

the hardware watchdog timer will detect this situation and restart the

gateway. Accordingly, the SMCWHSG44-G can provide continuous services.
