AddressFilter mismatch at the EndpointDispatcher error

I am using SOAPUI 4.0.1 for doing WCF Load Testing. I have just setup a new wsdl. In TestRequest Properties It is shopwing me correct endpoint, Interface and Operation. By default it automatically has generated a SOAF form xml. I have populated it with required values. But when I execute a test It gives me the following error message.

Body>
<s:Fault>
<s:Code>
<s:Value>s:Sender</s:Value>
<s:Subcode>
<s:Value>a:DestinationUnreachable</s:Value>
</s:Subcode>
</s:Code>
<s:Reason>
<s:Text xml:lang="en-GB">The message with To '' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree.</s:Text>
</s:Reason>
</s:Fault>
</s:Body>
</s:Envelope>

Please guide what i am missing here as I am new to this SOAP syntax.
