The setup that is shown in the LANTEST documentation could result in selective communication problems and thus can prevent updates on the test console or other such similar problems.

For instance, an issue observed with the past and current LAN tests causes LANTEST to disable the checksum offload while trying to communicate with the testcon on the same NIC. With checksum disabled, you will receive invalid packets which would be rejected by the protocol stack, thereby causing communication problems.

If you are testing the TCP/IP checksum offload feature of a NIC/driver, be sure that in the test setup, the (Windows) console can communicate with the test server on a different network (other than the network used by the test NIC).
