Pls ensure that multi-NIC or firewall is disabled.
pls check the gateway address when visiting outside server. Generally, it should be the
IP adress of the router. the gateway setting of module should be same with router's.
If still not work, pls do TCP Client test with our USR-TCP232-Test software, connect to
server and check whether it is connected
