there's a missing
'and"in lines 64 and 66 respectivelyunfortunately I could not make this work. Might be due to the use of /etc/network/interfaces, which has been recently replaced by dhcpcd.conf
have you tried in most recent version of raspbian and RPi3+?
This is the procedure for the newer systemd based Raspbian/Raspberry OS versions.
