Mitel SME Server V5 with ServiceLink manual Configuring Your Dhcp Server

Chapter 6. Installing And Configuring Your SME Server V5 with ServiceLink Software

There are two separate timeout values configured by each choice. One value is the length of time since the last HTTP (web) packet went through the server. The other is a more general timeout for any other types of packets. The difference is there because it is assumed that people reading a web page may take longer to go on to another web page, whereas users connecting to another service (such as ssh or POP3 to an external server) probably will be more active than someone using a web browser. The timeout values are shown in the table below.

Choice	HTTP Timeout	Other Timeout
Short	3 minutes	30 seconds
Medium	10 minutes	5 minutes
Long	20 minutes	10 minutes

Note that there is also the option for a Continuous dial-up connection. Choosing this option is basically equivalent to creating a permanent or dedicated connection, but only doing so through the use of a dial-up connection and a modem. One example of this use might be to set a Continuous connection policy during work hours and then some variable policy during off-hours and the weekend. Assuming that your ISP is okay with this arrangement and you can afford to do so financially , these settings would give your users the fastest response time as the connection would always be online.

6.13. Configuring Your DHCP Server

You now will be prompted regarding DHCP service. Your SME Server V5 with ServiceLink can be configured to provide DHCP service to your internal network. The DHCP server can automatically configure the other computers on your internal network with such parameters as non-routable IP address, subnet mask and gateway IP address. This reduces the risk of error and simplifies the process of configuring your network.

We recommend configuring your server to use DHCP to configure all of your network clients. You should not do this if there is an existing DHCP server on your network as there should typically be only one DHCP server per network.

6.13.1. Configuring the DHCP Address Range

Before the DHCP server is able to assign IP addresses to the computers on your network, you need to tell it what range of IP addresses it can safely distribute. As above, this section is pre-configur ed with defaults that are appropriate in most situations.
