ServiceLink Manual

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-conﬁgured with defaults that are appropriate in most situations.
