As your proxy server can obviously perform NAT (Network Address
Translation), you only need one official IP address for
the proxy server.
All your internal PCs can use 'illegal' IP addresses (or even
better the 'private' addresses like 192.168.*.*) internaly.
As people going to the Internet will use the proxy server,
the source IP address of the IP datagram sent to the Internet
will always be the one of the proxy server.
BTW, even if you do not use the MS Proxy, you can still use
the router used to connect to the Internet to perform NAT...
Last paragraph probably bears my employeer flagrance ;-)
