So, I went the cloudflare tunnel route. All that did was give me access to the Dolibarr program. I need to grant access to a specific location. (http://192.168.1.37:8036/public/payment/newpayment.php?source=invoice&ref=IN2505-0006) the invoice number will be unique for each order we send out. FYI, I used the official docker image in community apps. Thanks
