myGuard 7500GL 802.11g Security ADSL Router
Fast Ethernet Switch
A 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI
and MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or cross-over cable
can be used directly for auto detection.
Multi-Protocol to Establish A Connection
Supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516), and IPoA
(RFC1577) to establish a connection with the ISP. The product also supports VC-based
and LLC-based multiplexing.
Quick Installation Wizard
Supports a WEB GUI page to install this device quickly. With this wizard, end users can
enter the information easily which they get from their ISP, then surf the Internet
immediately.
Universal Plug and Play (UPnP) and UPnP NAT Traversal
This protocol is used to enable simple and robust connectivity among stand-alone devices
and PCs from many different vendors. It makes network simple and affordable for users.
UPnP architecture leverages TCP/IP and the Web to enable seamless proximity
networking in addition to control and data transfer among networked devices. With this
feature enabled, users can now connect to Net meeting or MSN Messenger seamlessly.
Network Address Translation (NAT)
Allows multi-users to access outside resources such as the Internet simultaneously with
one IP address/one Internet access account. Many application layer gateway (ALG) are
supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping,
NetMeeting, IP phone and others.
Firewall
Supports SOHO firewall with NAT technology, automatically detects and blocks Denial of
Service (DoS) attacks. URL blocking, packet filtering and SPI (Stateful Packet Inspection)
are also supported. The hacker's attack will be recorded associated with timestamp in the
security logging area. More firewall functions will always be implemented through updated
firmware releases.
Domain Name System (DNS) relay
Provides an easy way to map the domain name (a friendly name for users such as
www.yahoo.com) and IP address. When a local machine sets its DNS server with this
router's IP address, every DNS conversion request packet from the PC to this router will
be forwarded to the real DNS in the outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.
This dynamic IP address is the WAN IP address. For example, to use the service, you
must first apply for an account from a DDNS service like http://www.dyndns.org/. More
than 5 DDNS servers are supported.
