7 IP parameters configuration
Warning: parameters always have to be defined in full agreement with the network policies applicable
within your organisation (ask your network administrator).
The Ethernet port of the eWON® is configured in the factory with the following default parameters:
• IP Address: 10.0.0.53
• Subnet mask: 255.255.255.0
• Gateway: 0.0.0.0 (none)
Note: the default IP address for dial-up access (PPP) is different (202.0.0.240). This allows
simultaneous connection through both interfaces.
Whatever the access mode is (direct or dial-up), you will need these IP parameters to communicate with the
eWON®. If your device is inserted in a local network (LAN), one of the first things to do is to assign the device IP
parameters that are compatible with your network (ask your network administrator). The following chapter describes
how to edit these parameters by using the eWONCfg.exe utility. You can also edit the IP parameters with your
navigator and the Web site included in the eWON®.
Warning: normally you cannot communicate with a device for which you don’t know the IP parameters.
Therefore, there is a special tool (called “eWONCfg”) you can download from the eWON® Internet site
http://www.ewon.biz . Start this application once you have connected your eWON® to the network. The
application will scan the whole network and will identify all eWONs® that are connected, including their
IP parameters (Address and subnet mask) and their serial number. The utility allows also to edit the IP
parameters. IP parameters always have to be defined in full agreement with network policies applicable
within your organisation (ask your network administrator).

When connecting through a modem, the eWON® assigns a client address to the PPP interface of your PC. This
address has to be configured outside the range of addresses used within the LAN network of your organisation (ask
your network administrator). For example, if your organisation has 10.0.0.0 as basis address and 255.255.255.0 as
subnet mask, then you can use any address between 10.0.0.0 et 10.0.0.255. Contact your network administrator in
order to obtain an IP client address that is compatible with those of your organisation.
