# This PowerShell command sets 0 to System.Management.Automation.Tracing.PSEtwLogProvider etwProvider.m_enabled

  3. Optional: Associate a Elastic IP with the instance.
  4. SSH into the instance.
  5. sudo apt-get install pptpd.
  6. sudo vim /etc/pptpd.conf. Uncomment localip 192.168.0.1 and remoteip 192.168.0.234-238,192.168.0.245.
  7. sudo vim /etc/ppp/pptpd-options. Uncomment ms-dns and ms-wins. Change the IP to Google's DNS like this:
