This is getting ridiculous now, how many times have I said that you should not have two routers on the network at the same time. The server should not have it's own router, it should just be connected to a switch. The CenturyLink device should be set to act as a modem only, that should then connect to the RV042 which should connect to the DSH-16 (Please replace this with a switch, it's 2015, using a hub is ridiculous). There should be no router for the server, get rid of the BEFSR41, this is only going to cause confusion.
Please, go and teach yourself how networks work, you are doing this for your job, you should understand what you are doing and not be relying on us to help you do your job.
