Windows XP + Comcast's varying subnets

I have 3 computers right now, 2 with windows xp and 1
running linux. All connecting to comcast internet through
a hub. Each can grab an IP address from comcast's DHCP
server but they spread them all across different subnets,
making the internal network slow and harder to connect
to. I've tried to set up each computer with a private IP,
leaving the gateway blank.. then adding the same ip the
dhcp server gave me as a second IP, and using a 'route -p
ADD 0.0.0.0 MASK 0.0.0.0 <gateway> METRIC 1' command to
merge the 2 and use both the internet and the internal
network. This works, but because comcasts rules says I
can't have static IP's, I get in trouble and get
disconnected often enough. My linux box is able to grab
an ip from the DHCP server and add a private IP without
disturbing comcast, is there any way to do this through
windows XP? Thanks in Advance.

Trying to share files between computers with public IP addresses is
dangerous: it can give everyone on the Internet access to your files.

Does each computer need its own individual public IP address from
Comcast? If not, cancel all but one IP address and use a broadband
router to share that address between all of the computers. The router
will give each computer a private IP address in the same subnet as the
others.

If each computer needs a public IP address, to run a server or for
some other reason, here are some possible solutions:

1. Run a second protocol on each computer and use that protocol,
instead of TCP/IP, for file and printer sharing. Windows computers
can use IPX/SPX or NetBEUI for the second protocol. I don't know
about Linux.

2. Add a second network adapter to each computer, assign them all
private IP addresses in the same subnet, and un-bind file and printer
sharing from the first network adapter.
