So I'm in a situation where I am temporarily using an iPhone as my only Internet connection. It mostly works fine except for the fact that OS X Internet sharing will not assign DHCP IP addresses to the Ethernet port (and clients to the Airport Express) which is plugged into it. Previously I had the same hardware configuration sharing the Macbook's wifi to the Ethernet port without problem.

My current workaround is to bridge the iPhone USB connection to Ethernet in OS X, which as far as I can tell lets the iPhone assign everyone an IP address. This leaves me questions with things about Firewalls, NAT, etc.

My network looks like this:

[iPhone w/USB personal hotspot]--------USB-------[MacBook]-------CAT5--------[Airport Express Basestation]-------WIFI--------[PS4/iPad]

You're using a 3G/4G connection to give your MacBook an internet connection? Or am I confused?

Yeah this doesn't really make much sense. Wouldn't you just connect your devices to the WiFi hotspot provided by the iPhone without any bridging or an Airport in the way? There's no port forwarding or firewalls for you to manage because you're behind your carrier's router, you don't get an Internet IP address. They do the NAT, you get an internal IP, usually in the 10.* range.
