Running a Server from Dev Machine for development/testing purposes

I am trying to develop a Telegram Bot in Python on my dev machine. And I want the webhook call to route to the Python Server running on my dev machine, for testing.

• Find my public IP Address

  Invoke-RestMethod -Uri https://ipinfo.io

  Select -ExpandProperty ip

  50.35.66.240

• Find my laptop’s private IP Address

  get-netipaddress

  ? { $.AddressFamily -eq ‘IPv4’ -and $.PrefixOrigin -eq ‘Dhcp’ }

  Select -ExpandProperty IPAddress

  192.168.86.25

• Download OpenSsl precompiled binaries for Windows

  https://wiki.openssl.org/index.php/Binaries

• Generate Self-Signed Certificate

  ”[ req ]`ndistinguished_name = req_dn`n`n[ req_dn ]”

  Set-Content .\openssl.cnf

  .\openssl req -newkey rsa:2048 -sha256 -nodes -keyout tellthenaskbotprivate.key -x509 -days 365 -out tellthenaskbotpublic.pem -subj “/C=US/ST=Washington/L=Seattle/O=FUNGEE LLC/CN=tellthenaskbot.fungee.llc” -config (dir .\openssl.cnf

  select -expandproperty fullname)

• Go to Google Domain Manager and add an A record for tellthenask.fungee.llc pointing to my public IP Address.

• Go to Google Home Wifi Advanced Settings Port Management, and add a port forwarding rule to forward https traffic on public IP address to laptop’s private IP address.

• Run the Server with https:

  flask run –cert=.\tellthenaskbotpublic.pem –key=.\tellthenaskbotprivate.key -p 3000 -h 192.168.86.25

• Test TCP connection from outside:

  Test-Netconnection tellthenask.fungee.llc -Port 443
