3.3.4.2.6 Ethernet Gateway behavior<br />
On the <strong>eWON</strong>, it is possible to define a default gateway on the ethernet interface.<br />
First we must consider 2 cases.<br />
• The <strong>eWON</strong> has 2 ethernet interfaces (2005/4005/2005CD/4005CD/2104/4104)<br />
In this case, the gateway is active only while the WAN interface is connected.<br />
The <strong>eWON</strong>-ADSL must be considered as an <strong>eWON</strong> with 2 Ethernet interfaces.<br />
The ADSL interface is a WAN interface.<br />
• The <strong>eWON</strong> has only 1 ethernet interface.<br />
3.3.4.2.6.1 <strong>eWON</strong> with 2 Ethernet interfaces<br />
General Reference Guide <strong>eWON</strong> Configuration<br />
• Normal behavior<br />
The Ethernet gateway is configured only when the ethernet WAN connection is established.<br />
The Ethernet WAN connection is established on demand when the <strong>eWON</strong> has no route for a packet, or always when the “Maintain<br />
connection” option is checked in the “Internet connection' configuration”.<br />
• Gateway during an incoming PPP connection<br />
There is a special case when:<br />
• WAN Ethernet connection is enabled<br />
• Incoming PPP is enabled<br />
• Use incoming for outgoing is enabled<br />
In that case, when the incoming communication is received, the <strong>eWON</strong> will<br />
try to configure the PPP connection as the default gateway. This will happen<br />
only if the WAN connection is not enabled at that time.<br />
So, if the PPP connection is established and the WAN connection is not<br />
active, the PPP connection becomes the gateway. If the WAN connection is<br />
active, then the PPP connection will not become the gateway.<br />
3.3.4.2.6.2 <strong>eWON</strong> with 1 Ethernet interface<br />
• Normal behavior<br />
In that case, if a gateway is defined, it will become the default gateway only if the Internet access is set to “No internet access”'<br />
If the “Network connection” is configured to something different from “No internet access”, the Ethernet gateway will not become the default<br />
gateway, and a warning will be issued in the event log:<br />
“Ethernet gateway not used (incompatible internet connection)”<br />
• Gateway during an incoming PPP connection<br />
During the incoming PPP connection, the default gateway is normally not changed, except if the 'Use incoming for outgoing' option has been<br />
selected.<br />
In that case, the default gateway becomes the PPP connection during the<br />
incoming connection.<br />
The default gateway is reconfigured to the Ethernet gateway when the PPP<br />
connection ends.<br />
