Port Options

Figure 6.  Port Options

Use this field to select the type of connection validation 

to perform. When set to ICMP, the XC-DPG503 sends 

out ICMP echo requests.  When set to HTTP, the XC-

DPG503 requests web pages.
Alive Indicator

This is the IP address used to check if the WAN 

connection is operational. When using HTTP, put in a 

valid IP address of a web server. When this field is blank, 

the ISP gateway IP address is used.

Note: This is not used for PPPoE connections.
MTU

The Maximum Transmission Unit is used when 

determining the packet size to be used on the WAN 

interface. Normally, this does not need to be changed, but 

if your ISP advises you to use a particular MTU, enter it 

here.

When set to Enable a connection will be established 

whenever outgoing WAN traffic is detected. If not 

Enabled, you must establish a connection manually.
Auto Disconnect

This determines when an idle connection will be 

terminated. Enter the required time period.
Echo Time

This determines how often an Echo request is sent to the 

PPPoE server. The Echo request is used to determine if 

the connection is still valid. Normally, there is no need to 

change the default value.
Echo Retry

The number of time the Echo request will be sent if there 

is no response to the first request. Normally, there is no 

need to change the default value.

When set to Enable, this WAN port does not use NAT & 

Load Balance function when LAN/WAN IP have the real 

IP addresses on the same network segment.

Traffic Management
Strict Binding - When a WAN port connection is 

disconnected, the packets will not go to another WAN 

port.
Loose Binding - When the WAN port connection is 

connected, the packets will go another WAN port.
Load Balancing - This will mix real and private IP’s on 

the LAN side doing the load balancing.
