Your ISP's dhcp service will only assign an address to the machine
connected to their network; the Win machine in your case. The machines on
your network will need their own addresses, which can either be hard-coded
into a "hosts" file or assigned by a local dhcp server on your network.
Having a dhcp server on your network is probably the best long term
solution, but it's your choice. It doesn't matter which machine provides
the dhcp service. If you're more comfortable with Windows there's no
reason why you can't do it there.

This should be the ip address of your external NIC.

Do you have NAT (network address translation) working on the Win machine?
Without that, machines behind the gateway will not be able to access
things on the internet.

FWIW, setting this up in linux instead of Windows is quite simple in my
experience.
