This is starting to be ridiculous. My router restarts itself when I just want to use VPN tunnel through it. Your page https://www.tp-link.com/au/support/contact-technical-support/#E-mail-Support says on submit Submitted failed. So after all the work with filling the form boom, gone. I have spent hours with this rubbish first troubleshooting without suport, then with chat support, and I am starting to be really frustrated. Wasting my time on this. At least fix your disfunctional form, thank you very much!
