Used $SCRIPT inside crontab function due to $0 not existing (scope).
Verified all other packages installed (except the mispelled one)
Fixed sed command to modify ssh port for ssh config.
Fixed home dir ownership for supplied user.
Fixed firewall configuration forwarding bugs (forwarding rules still untested!)
