Some are much easier than others; e.g., SonicWALL has a specific configuration
option for the use of multiple public IPs on multiple internal clients while
preserving firewall, filtering, and management functions.

It may be a 100 Mb connection, but the available bandwidth is almost certainly
much less than that.

That's because they work as a bridge.

That depends.  ISP DHCP implementations based on MAC addresses only work well
if the router doesn't interfere.  There are different potential problems if
DHCP Client ID is based on something like hostname.

Easier to simply get a true Access Point (bridge).
