Not being able to lease DHCP addresses is a unit/machine specific
configuration issue.

It can be client OS dependent as well, if the DHCP server is a skosh buggy.

Also, the client needs a direct connection to the DHCP server. DHCP
requests won't normally propagate through a router (or a PC running
Internet Connection Sharing).

The DHCP requests propagate just fine through my routers and switches.

DHCP will propagate fine through a hub or switch, but it can't be routed
as the client lacks an IP address (that's why it's issuing a DHCP
address).

DHCP requests are broadcast, typically with 0.0.0.0 as the source address.
The server uses the source MAC address to choose an IP address. Replies
are sent back to the MAC address from which the request originated. All of
this operates at the link layer (ethernet, WiFi) rather than the IP layer.

You can, however, run a DHCP relay on a router. This is essentially a
proxy server for DHCP. It will work regardless of whether the "router" is
actually a router or just a multi-homed host. Even if it is a router, it
isn't *routing* DHCP requests.

Presuming that the manufacturer is labeling their equipment correctly
it is a switch. See:
