Please always remember to supply every information of what you have on your networking equipment. You have left out one important information, and this case I wouldn't be able to help you UNLESS you give us your DSL modem information!
True business every modem is different when it comes to set up, some are just basic which can be set up just on router, while other modem need to have different way to set up in order for all three, VP, router, and Modem to work together right. Finally, the reason is often if set up is not right, the port will definetly close and VP will not be able to communicate outside of the networking.
