TCP doesn't enter into it, and NATted IPsec uses UDP port 4500. Also, one end-point (usually the "hub" of your star topology) can have a fixed address, and everything else can be dynamic. In that case, only the spokes of the star would initiative connections (because the hub obviously wouldn't know how to address them).
