In the course of the campus network construction, most schools are based on higher prices, features more routers to LAN users to share fast ADSL or HDSL access to Internet and LAN with LAN connectivity, but the higher price and management to maintain the degree of difficulty to the school brought some problems, the experience provided by this article may give the school funding tight LAN to share Internet access bring some inspiration.
As our school campus recently to achieve the goal line, so to set up local area network to share broadband Internet access. The way in achieving the shared, we no longer use the traditional Windows 98 + Wingate to achieve multiple machines to share Internet access method.
This is because:
(1) requires the proxy server's hardware configuration is relatively high, the server software running on a number of large, easily lead to network instability.
(2) If the proxy server is a problem, the LAN computer users can not share Internet access, and this will affect the normal teaching duties.
(3) set the proxy server software is too much trouble, the proxy server a long time online, is not conducive to LAN security.
(4) If we want the user to access a computer outside the network's Web or FTP within the LAN server, Internet proxy method implementation becomes more difficult. Thus, the Internet through a proxy server, there are a lot of inconvenience and restrictions, so we have chosen to share a broadband Internet router. This method was easier to implement, practical.
Here, we have to introduce this approach.
Router Selection
Share broadband Internet access in the formation process, we chose IP502H broadband router, broadband router, this allows all LAN users to share fast ADSL or Cable Modem to access the Internet, also supports LAN to LAN connection. It has 10M/100M adaptive Ethernet interfaces, is ideal for schools, access to the Internet needs of SMEs and Internet cafes. Management with Web interface is easy to use. Built-in DHCP server, so you no longer need the administrator to configure the network, they worry and effort.
In addition, its biggest advantage is not only can save the original Taiwan made high-profile gateway routing computers, and LAN users Internet connection speed of response when the obvious way than through a proxy server fast, stable performance, users can always dial-up . This broadband router, compact, low power consumption is also suitable for long-line work boot, without accounting for space, and its price higher than a configured proxy server is much cheaper.
Installation and commissioning
IP502H with ADSL and the connection hub or switch as shown: the ADSL Modem to connect to IP502H broadband router, broadband router and then IP502H 10M/100M adaptive Ethernet interface and connected to a switch or Hub, so we on the realization of a shared Internet hardware installation. Finally, as long as the host to connect to the switch to install the appropriate ADSL dial-up software, set the relevant user name and password, we can share the Internet through a broadband router.
