I set up my tower years and years ago just to act as a redundant back up, and have no memory of how or why I set up my network settings on my router. I had set my old router to PPOE and used my internet providers user name and password. I just signed up for a new internet provider and I would like to standardize my tower to work with the new provider. Inasmuch, I believe I should set my wifi router to bridge mode instead of "DCHP and NAT" but once I do so I can no longer see my tower. In oder to see my tower I need the router to be in "DCHP and NAT" and set up a DCHP reservation. But if I set it up that way I get a warning that there is a "double NAT". Ultimately I have no idea what I am doing and would appreciate any help. I've provided a couple screen caps in someone can help me set things up properly. Thank you in advance.
