gufw is still available in the list of installed apps as "Firewall Configuration".
It is intentionally not available in the GNOME Settings app since that is reserved for GNOME settings (and select integrated Ubuntu settings). Note that currently you will need to use the "Ubuntu on Xorg" session since this app doesn't currently support Wayland as required by the default "Ubuntu" session in 17.10.
