USB VPN & Firewall Adapter DHCP Figure 7-26 From the DHCP screen, shown in Figure 7-26, you can configure the Adapter as a DHCP Server. A Dynamic Host Configuration Protocol (DHCP) server automatically assigns an IP address to your PC on your network for you. Unless you already have one, it is highly recommended that you leave the Adapter enabled as a DHCP server. If you disable DHCP, remember to assign a static IP address to the Adapter. Starting IP Address Enter a value for the DHCP server to start with when issuing IP addresses. This value must be 192. 168. 1. 2 or greater, because the default IP address for the Adapter is 192. 168. 1. 1. 56 57 Instant Broadband® Series Number of DHCP Users (Optional) Enter the maximum number of PCs that you want the DHCP server to assign IP addresses to. In order to determine the DHCP IP Address range, add the starting IP address (e. g. , 100) to the number of DHCP users. By default, as shown in Figure 7-28, add 100 to 50, and the range is 192. 168. 1. 100 to 192. 168. 1. 149. Client Lease Time The Client Lease Time is the amount of time a network user will be allowed connection to the Adapter with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be "leased" this dynamic IP address. DNS The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. [. . . ] It allows a user at a terminal or computer to log onto a remote device and run a program. TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocol that has no directory or password capability. Throughput - The amount of data moved successfully from one place to another in a given time period. 86 USB VPN & Firewall Adapter UDP (User Datagram Protocol) - A method (protocol) used along with the IP (Internet Protocol) to send data in the form of message units (datagram) between network devices over a LAN or WAN. While IP takes care of handling the actual delivery of the data (routing), UDP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient delivery over the network.
