At one point in time it was sufficient to

  sudo apt-get install ipmasq dnsmasq

and your system would share its uplink connection (properly NATed) to
all other machines on the internal LANs.

I'm pretty sure it should still work.

You might also want to enable dnsmasq's built-in DHCP server, if you
don't have one set up already, to get the internal LAN machines
automatically get the correct IP, DNS and gateway addresses.
