I am confused and hope someone can help me to understand what is going on. Let me start by saying that everything is actually working - I just don't really understand why and it's not working in the way I expected. I have Verizon FIOS Internet & TV. As part of the service, they provide a router with a coax connection on it. This connection is necessary for some of the TV services (Video on Demand, some of the program guide.) I'd been using their router, an older Actiontec, and it dropped dead - wouldn't power on any longer. In order to get back up temporarily, I pulled a Linksys WRT54G out of the closet and set it up in place of the Verizon provided router. Once I remembered to configure it as PPoE with any random username/password, it worked fine. Meanwhile, Verizon got another Actiontec on the way to me. While I was without the Actiontec, I couldn't use any Video on Demand services on my set top boxes as expected. Using the old Linksys for just a day, I remembered how much I liked the Linksys routers. I never did like the Actiontec router - the web interface is awful and you don't have tons of 3rd party tweakable firmwares to play with like you do on the Linksys. Because of this I decided when the Actiontec arrived, I'd try connecting the WAN port on the Actiontec to one of the LAN ports on the Linksys and see if that worked. My thinking was that the Linksys would just hand the Actiontec an IP address via DHCP and the Actiontec could then get to the Internet and do whatever it needed to do for the set top box stuff. My configuration is: Actiontec WAN->Linksys LAN->Linksys WAN->Box on outside of house What I do not understand is how/why the Actiontec is actually getting a "real" IP address - it's got a 173.x.x.x address - it did not get that address from the Linksys. It seems to be using PPoE to go through the Linksys directly to the Verizon CO (or whatever you call what is past the box on the outside of my house) and get an IP address. My Linksys is also using PPoE to go to (I assume) the same place and get an IP address. Each device has it's own different 173.x.x.x address and everything works just fine. I had expected that I could configure the Actiontec to get an address via DHCP instead of PPoE and have the Linksys hand it an address - I tried that but it didn't work. When I was messing around with the Actiontec, one thing I did do was change the IP range it was using to 192.168.2.x instead of 192.168.1.x since the Linksys was using that range. Once I did that, the PPoE magic happened and everything just worked. I don't really see any downside to this assumning Verizon doesn't care that I happen to have two IP addresses. I am not sure how I'd know if they care - I guess at some point they'd let me know or something. Sooo can anyone explain to me why it's working this way? How can the Actiontec not even have an IP address assigned from the Linksys yet make it all the way past/through the Linksys to the Verizon CO to get a real IP address?? Edit: To clarify, when I was messing with the Actiontec, I had to plug a laptop into one of the LAN ports on it. I can't seem to get to it's interface in any way unless I do that which is fine with me, like I said I don't like its interface anyway.
