everything you need to get the machines on your network connected to the Internet
over your ADSL broadband connection.
The WebShare 111U complies with ADSL2+ standards for worldwide deployment and
supports downstream rates of up to 24 Mbps and upstream rates of up to 1 Mbps. It is
designed for small office, home office and residential users, enabling even faster
speed Internet connections. User can enjoy ADSL services and broadband multimedia
applications such as interactive gaming, video streaming and real-time audio much
easier and faster than ever before.
The product supports PPPoA (RFC 2364 – PPP (Point-to-Point Protocol) 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 ISP. The
product also supports VC-based and LLC-based multiplexing.
It is the perfect solution to connect a small group of PCs to a high-speed broadband
Internet connection. Multi-users can have high-speed Internet access simultaneously.
This product also serves as an Internet firewall, protecting your network from being
accessed by outside users. Not only provide the natural firewall function (Network
Address Translation, NAT), it also provides rich firewall features to secure user’s
network. All incoming data packets are monitored and filtered. Besides, it can also be
configured to block internal users from accessing to the Internet.
The product provides two levels of security support. First, it masks LAN users’ IP
addresses which are invisible to outside users on the Internet, making it much more
difficult for a hacker to target a machine on your network. Secondly, it can block and
redirect certain ports to limit the services that outside users can access. For example,
to ensure that games and other Internet applications will run properly, user can open
some specific ports for outside users to access internal services in network.
Integrated DHCP (Dynamic Host Control Protocol) services, client and server, allow
multiple users to get their IP addresses automatically on boot up from the product.
Simply set local machines as a DHCP client to accept a dynamically assigned IP
address from DHCP server and reboot. Each time local machine is powered up; the
router will recognize it and assign an IP address to instantly connect it to the LAN.
