sbs-2008

We have a Windows SBS 2008 machine. Several ports need to be forwarded from the router to the server (the machine hosts a FTP server, a Web server, and we need to be access it through Remote Desktop).

We recently changed routers (from SpeedTouch to Huawei EchoLife HG520s). With the previous router, port forwarding worked fine. Now, after setting up port forwarding on the new router, nothing works anymore. Can anybody help me with directions on how to diagnose/troubleshoot port forwarding problems on the router and in Windows SBS 2008? E.G.: after forwarding a port in the router interface to the internal IP of the server, how can I see in the SBS 2008 logs if the request is properly forwarded to it?
