(They were not connected to the internet modem because for whatever
reason, directly connecting them made them very unstable and prone to
crash.) But, nevertheless, the old hardware could use the mint box

Hi Dan, what you want to do, used to be called IP masquerading and
pretty much everyone did it on their linux box to share their dial up
connection to other computers on their lan. Now it seems to be called
NAT network address translation and the possibilities of what you can do
have multiplied tremendously, but the simple use case is still there.
From memory I used shorewall to configure iptables but it is pretty
simple to do manually. And has the advantage of not having layers of
complexity on top of it to debug if something goes wrong.
Here's a howto I found, old but it looks like it should still work
