OpenVPN and Pihole - Unable to access web interface

Help
1

Please follow the below template, it will help us to help you!

Expected Behaviour:

Setup Pihole with OpenVPN on AWS Lightsail VPS. Working fine. I can connect to the VPN, access web sites, etc. However, after inputting the firewall rules as outlined in the documentation here:

I am unable to access the Web UI WHILE connected to the VPN through the tun0 interface.

Actual Behaviour:

web interface site hangs and unable to access while connected to VPN. My understanding is that I should be unable to access the web interface when not connected to the VPN. However, once connected, I should have access to the web interface.

Thank you.

You need to remove this iptables line.
See how it works after that.

Update. SOLVED It works perfectly fine just following the directions in the tutorial. I was trying to access the web interface from the public facing IP rather than the internal IP. As such, it was hanging as it should. Tested as follows:

Not connected to VPN
Access web interface using internal IP and it is not accessible

Connected to VPN
Access web intergace using internal IP and works fine.

All good. Sorry for posting this. It was my error. All works fine. Thank you
