    Your solution depends upon the type of network you're designing.

    If you have only one router on your network and it is set to bridge mode, your network (wired or wireless, or both) will be active but will not be open to connecting to your internet access. If the single router is not set to bridge mode, your network will be able to be connected to your internet access.

    When your network will contain more than one router, select bridge mode for each of the additional routers if they will be connecting to a router or other network device that is already using DHCP and NAT to provide IP addresses to computers on your network.

    You can use any one of the routers to be the DHCP/NAT server as long as the others are setup in bridge mode. You will usually want to choose the router with the greatest serving capacity to be your DHCP/NAT server. An AirPort Extreme or Time Capsule's network is limited to serving up to 50 users, while an AirPort Express is limited to serving up to 10.

    What bridge mode really does is to allow additional routers to connect to the network without conflicting with the DHCP/NAT server. Additional routers may extend the network's wireless range and/or enable additional wired connections for clients and devices.

  • Bridge mode will allow your modem to assign the IP address. You need the AirPort to assign the IP address if you want to use Back to My Mac with MobileMe. If not, I don't think it matters.
