Then use redirect_port and/or redirect_address in the natd configuration to pipe through the services from the servers to the outside world. This buys you an implicit firewall for your servers (==good). The QTS server will probably require redirect_address so you may want to craft some firewall rules to protect it individually. This gets around the sticky broadcast problems you need for conventional AppleShare (you really should use AppleShareIP, it's faster and much more stable). Also pick up a good extensible switch, like a HP ProCurve 4000M, and plug everything into it. 80 ports for $1000 with rebate and is a fantastic switch. Do you have a T1/sync serial card that you're plugging the T1/CSU/DSU through or do you have ie. a Cisco 2600 that's taking care of that?
