I haven't worked with the Verizon gateways, but configuring the device as a simple bridge might require that the Time Capsule be setup to furnish the PPPoE service. You won't know until you try.
If you are not able to "Connect Using - Ethernet", then that would be an indication that you would need to instead "Connect Using - PPPoE". In this case, you'll need to enter your user name and password that you have established with the service provider in the Time Capsule setup configuration. Be sure to leave the Service Name area completely blank if you setup using PPPoE.
If you are able to "Connect Using - Ethernet" and you configure the Time Capsule to "Share a public IP address", you may see a warning during setup that this is producing what is known as a Double NAT on your network. This is normally not too serious, unless you are trying to setup online gaming, which requires a different type of NAT setting.
Yes, if you're using your modem/router in bridging mode, so that it's just a dumb modem, you should select "Connect Using PPPoE" and add your ISP log-in details. I've found that changing "Connection" from "Always On" to "Automatic" helped with random disconnects, but that might be just something to do with my router.
So it is working at the moment. However, I do get a "Dual NAT" error. I have talked with Verizon about this and they indicate that this is expected. I went into the Verizon DSL Modem and turned off NAT but in that case, the connection to the internet was lost entirely.
So, while I am trying to deal with the "Dual NAT" thing, I am continuing to use the network as is. So far, everything is working. From the Xbox and PS3 all the way down to my Vonage phone service continue to work.
My main motivation right now is to get the Dual NAT thing solved so that all the MobileMe features will work. Currently, I cannot get back to my mac due to this Dual NAT problem.
The modem is providing NAT service and so is the Time Capsule, so that's why you are getting the Double NAT error. Based on the information in your post, you may not be able to get the Verizon gateway setup as a bridge-only modem.
In a situation like this, the only way I have been able to solve the issue is purchase a simple modem only and configure it as a bridge. Then you need to setup the PPPoE service on the Time Capsule. This will eliminate the Double NAT on the network.
