Proxying and forwarding



I've got something in mind that I want to make sure is sane before I
go try to impliment it on my home network.

First, have a private network.  192.168.0.0/24.  Transparent proxying
of outbound HTTP requests.  Easy enough, I've done it before.

Now, getting an IP.  Client machine A sends out a DHCP request with a
known hostname.  Gateway gets the request, makes request on the
internet connection with the same MAC as the client.  Gateway gets
response back from ISP, assigns a local IP to the client and forwards
everything for the new public IP to machine A.  Client machine B sends
out a DHCP request without a hostname.  Gateway assigns local IP
without going to the ISP.

The idea I'm ultimately getting at is isolating the traffic on my home
network from the public network, while not breaking things that might
need to phone back in for the people who live here (acting like
they're not NAT'd and firewalled, basically), while still allowing
VMWares and machines brought by visitors to get online without getting
a public IP.

Is this workable?
