Flexible Setup
For ease of installation and to meet your networking requirements, the Global Chalkboard is available in a variety of setup options. This flexibility includes the following configurations: Internet (2 or 3 Ethernet), Internet Gateway (PPPoE), Proxy Only, URL Filter Server, and Transparent Bridge (with or without firewall).Internet Gateway (2 Ethernet)
- This Global Chalkboard includes a LAN firewall, Web caching, filtering, the Web Library, and remote administration. It is compatible with many forms of Internet access, including ISDN, DSL, Cable, and T1 and works with an external router.
Internet Gateway (3 Ethernet)
- This Global Chalkboard requires the installation of a third network card. Depending on the system, this third network card may be pre-installed and provides a separate physical network. This network can be used as a DMZ for the protection of public servers such as a Web or an e-mail server, or it can be used as a separate internal network. For both networks (depending upon the setup), this Global Chalkboard includes the LAN firewall, Web caching, filtering, the Web Library, and remote administration. This Global Chalkboard is compatible with many forms of Internet Access, including ISDN, DSL, T1 and works with an external router.
Internet Gateway (PPPoE)
- Point-to-Point Protocol over Ethernet (PPPoE) is used by some DSL-based ISPs to establish communications. If using a DSL line, check with the ISP to see if they use PPPoE. If they do use PPPoE, it must be enabled. Remember to remove any existing PPPoE routers on the network and plug the system directly into the DSL modem. This Global Chalkboard includes a LAN firewall, Web caching, filtering, the Web Library, and remote administration.
Proxy Only
- In this configuration, the system is not in the direct path of network traffic. It sits adjacent to a router. The Web browser on each of the workstations needs to be configured with a proxy setting so that all Web requests are directed to the system. The DNS setting on each of the workstations also needs to be pointed towards the IP address of the system to properly resolve the system interface addresses. The system then performs Web caching and filtering. This Global Chalkboard also includes the Web Library and remote administration.
URL Filter Server
- Use this selection if a Cisco product (that supports the URL-filter command) is on the network and the Global Chalkboard will be used for filtering only. In this configuration, the system is not in the direct path of network traffic. Instead, it is adjacent to the Cisco product and is used for filtering Web requests. This Global Chalkboard also includes the Web Library and remote administration.
Transparent Bridge
- In this configuration, the Global Chalkboard is in the direct path of network traffic. All traffic flows through it, but only Web and DNS requests are intercepted. The system performs Web caching and filtering. This Global Chalkboard also includes the Web Library and remote administration.
Transparent Bridge with Firewall
- In this configuration, the Global Chalkboard is in the direct path of network traffic. All traffic flows through it. The system acts as a Web cache, filter and firewall. This Global Chalkboard also includes the Web Library and remote administration.
Acceptable Use Policy (AUP) Splash Screen
- This feature allows schools to create a WiFi hotspot for a portion of their network. (This can be especially helpful when a guest at your school needs access to your network.) Your school may wish to institute an AUP splash screen to notify users of your Internet guidelines or any other vital information. For flexibility in administration, specific computers and/or IP ranges of computers can be excluded from receiving the AUP screen.
