If one of the computers has a second network card (or if none have, install
a second card in one computer).
Connect this card to the Router of the other network and configure it as

Then Bridge the two networks in the computer with the two Cards.
This page describe bridging between two network it uses USB as an example,
but the principle is the same for two regular Networks.
