  My telephone company tells everyone to put the modem in bridge mode and then when using my Linksys router to put PPPoE on that and that (the Linksys router) is where I enter in my DSL key and e-mail address that my ISP gave me, so when I replace the Linksys with the Time Capsule which mode would I use? My modem would still be in bridge mode so would I put Time Capsule in DHCP or Bridge mode? Thanks!

Thanks for the help Bob. First thing I have to worry about is getting the Time Capsule first There won't be any double NAT right? The ISP wants everyone to bridge the modem and I guess that automatically disables DHCP on the modem because when it's put in bridge mode it acts as a dumb modem and all the authentication is done on the Linksys. You select PPPoE on Linksys and that's where you put in your DSL key & email and then a little box DHCP is checked right under PPPoE. Is this the best and most efficient way to set it up. I guess it has to be if your ISP tells you you have to bridge the modem.

 

   It seems as though I was getting confused with the Time Capsules screenshot and the Airport that you showed me above. But what about the Time Capsule? If I use Airport to set it up will I still get that box that comes up on the Time Capsule where it show DHCP and Bridge buttons? or will that be bypassed when just strictly using the Airport? If not what and I do get the box that comes up with DHCP and Bridge on the Time Capsule what would I have to choose on that providing that whole box won't be bypassed by setting up with Airport or not?

 

   I was getting the Time Capsule box confused with the Airport. I'ts because I don't have the Time Capsule yet and all I ever saw on the web was the Time Capsule box and finally realised that what you were showing me wasn't Time Capsule but Airport. So will this 2 button Time Capsule box be bypassed when set up like this or will a box come up from Time Capsule where even though doing PPPoE on Airport I'll still have to check either DHCP or Bridge in Time Capsule?

If the modem is configured in Bridge Mode and the Time Capsule is setup to connect using PPPoE, there will not be a Double NAT.

 

When you get the Time Capsule, all you need to do is connect the modem to the WAN port on the Time Capsule and open AirPort Utility.

 

AirPort Utility will ask a few basic questions like what you want to name the Time Capsule and what name you want to use for a wireless network and password.

 

AirPort Utility will automatically detect that the modem is in bridge mode and tell you that the Time Capsule will be setup to connect using PPPoE. Enter your ISP credentials and follow a few more simple guided steps.

 

You will be amazed at how simple and quick the setup will be.

    The Time Capsule will automatically be in the correct Router Mode of DHCP and NAT when it is configured to Connect Using = PPPoE.

    Thanks for your response. I don't have the Time Capsule yet but saw screenshots of it on the web. Only 2 options I see are a DHCP or a Bridge button. Where is it that you look to put it into PPPoE or you don't have to?

    What operating system do you have installed on the computer that will be used to configure the Time Capsule?

       I have the new 2012 (non-retina) MacBook Pro operating Mountain Lion 10.8.2 I just noticed this looks like you have to set up Airport on the Mac which you normallly wouldn't do with a Linksys. Is this the actual Time Capsule screeshot or the Airport untility that has to be set up? You don't need Airport setup for a Linksys and what I think I'm seeing here is not the Time Casule with the 2 buttons DHCP and Bridge button. This looks like you have to install Airport to use with Time Capsule am I right. This screenshot is of the Airport and not the Time Capsule right?

    A Time Capsule is an AirPort Extreme with a built in hard drive so the setup would the same for both devices.

     

    The previous screenshot is from AirPort Utility 5.6, the application that is used to setup the AirPorts and Time Capsule on Macs using the Snow Leopard and Lion operating systems.

     

    Mountain Lion uses AirPort Utility 6.1, which is already installed on your Mac.  Look in Macintosh HD > Applications > Utilities > AirPort Utility.  You won't see anything on the screen there until you have the Time Capsule.

     

    The screenshots are a bit different in AirPort Utility 6.1, but will look like this once you have the Time Capsule setup using the configuration "wizard" in AirPort Utility.

     

    Since you willl be using the Time Capsule to provide the PPPoE connection service, the modem would remain in bridge mode as it is now.

    I forgot to mention even though the modem is in bridge mode and the Linksys is set to PPPoE and my DSL password and e-mail address is entered in on the Linksys right under PPPoE setting there is also a box that is checked that says DHCP on the Linksys right under PPPoE. The guy from Linksys told me to leave that checked. I forgot you don't need to set up Airport if your using a Linksys. Just connects like my old Dell did. But since that checkbox DHCP is checked on the Linksys under PPPoE then I guess your above screenshot is the equivalent to the Linksys in where under the network tab I'd have to check DHCP & NAT right. DHCP is disabled when you have the modem in bridged mode right so that you don't get double NAT right? So your screenshot above where it says under the network tab would be like on the Linksys wherer right under PPPoE it has the DHCP box checked. It would be like equivalent to that right. The settings being equivalent to the Linksys right?

    Right

    Right

     

    So you screenshot above where it says under the network tab would be like on the Linksys wherer right under PPPoE it has the DHCP box checked. It would be like equivalent to that right.

    Right

    Right

     

    If you setup the Time Capsule like the screenshots illustrate, everything will be correct.
