In 2016, i had a computer with mint on it (which is a form of ubuntu),
and
it was connected to an internet modem. There was a super simple gui on
it
that i could use to share that connection with some older hardware that
were not directly connected to the internet modem. (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 with no
configuration
on my part, and get out to the internet through it.
Now, as it happens, i'm planning on upgrading that mint box to debian.
In preparation for that, i'm trying to share the internet with them
using
another box, which has debian on it, and which is connected to the
internet
modem. The debian box has some address like 192.168.*.* on the
internet
modem network, and an address like 10.*.*.* connected to the old
hardware,
and the two networks have no direct connection, they just both hook up
to
my debian machine (one on the motherboard's ethernet, and one on a
usb/ethernet device).
For the old hardware, i can specify the address, a gateway, and a host
for
dns (all done by ip). I would choose the ip of the debian box for both
the
gateway and the dns, and i'd take the ip address of the old hardware to
just be something unused (no need to run dhcpd on the debian box, i
think).
So i just need to know what to do on the debian box so that it can
field
requests to get ips from host names on the internet, and forward
packets to
the internet modem. Hopefully, it will be some simple tool like
nm-connection-editor, but maybe it has to be a series of commands. If
it
is a series of commands, what are they?
TIA for any info!
