Appendix D
Configuration File
The Web Interface enables the most common deployment scenarios to be configured and managed.
However more advanced configurations may require editing of the device configuration file.
The configuration file comprises of section headers and name value pairs. The configuration may include
comments lines but these will be lost if the configuration is edited using the web interface. A comment
always starts on a new line and the first character must be a hash, e.g:
# This is a comment - it will be lost if the configuration is edited using
# the web interface
A new section header starts the configuration of a feature or group of settings, a section header always
starts on a new line and is enclosed by square brackets (e.g. [sys]) It is followed by one or more name value
pairs. Name value pairs always start on a new line and the value part is enclosed by quote characters (e.g.
hostname="imo4-xxxxxx.build.ems-imo.com"
)
Names are formed by using the device or option name, followed by the index of the device or option if there
is more than one. The name may then be further extended by adding any sub-options.
For example the name to set the start IP address of the DHCP server for the second Ethernet port is:
eth1dhcpstartip
The [sys] section set a few system wide options. The only option that must be set is the "hostname" for the
router.
[sys]
hostname="imo4-xxxxxx.build.ems-imo.com"
timezone="GMT"
ntpserver="pool.ntp.org"
dnsserver="8.8.8.8, 8.8.4.4"
The [display] section configures what is shown on the front display of the unit.
With this you can enable or disable status display for the different system functions.
Each option can be set to yes or no.
[display]
time="yes"
tunneling="yes"
wan="no"
mobilerouter="yes"
The [lan] section configures the physical and logical networks interfaces.
The i-MO 310 and 540 appliances have 6 Gb Ethernet ports plus an optional wireless 802.11 b/g/n wireless
interface. The GbE interfaces are named eth0 through eth5 and the wireless interface is named wlan0.
