I'm getting AT&T DSL soon, and they offer either a regular DSL modem, or a modem that also includes a wireless router. I'm thinking of getting that wireless router, and then connecting my Time Capsule to it, and have the Time Capsule act as the "real" router, with firewalls and port forwarding configured and stuff. I know I can have the modem-gateway act as a dumb gateway, no NAT or DHCP or anything, and treat the Time Capsule as the default host (and hence giving the Time Capsule the public IP address). But I'm wondering if I can do it so that the Time Capsule is the only one connected to the modem? For security reasons and so forth. Is this possible?
