I've tried the method mentioned here, using xinput:
sudo xinput set-prop 12
which gives
Device 'SYNA8018:00 06CB:CE67 Touchpad':

Then, using the following works to reverse scrolling:
sudo xinput set-prop 12 327 1
However, this isn't permanent and reverts after a reboot. So I've tried the following:
sudo xinput set-prop 12 328 1
This should put the default as natural scrolling, but I get the following errors:
X Error of failed request: BadAccess (attempt to access private resource denied)
Major opcode of failed request: 131 (XInputExtension)
Minor opcode of failed request: 57 ()
Serial number of failed request: 20
Current serial number in output stream: 21
Even though I used sudo?? How to enable it anyway? Or does there exist another way to enable natural scrolling?
