I recently installed Pi-Hole + PiVPN (OpenVPN) on a RPI at my home. I used this guide to set it up and it works great, traffic from the VPN is routed thru the Pi-Hole; however when connected to the VPN via my Pixel 2 with the OpenVPN Connect app I cannot send or receive text messages. I have tried disabling the Pi-Hole to determine if the problem is with the VPN or Pi-Hole and the problem persists.
I am hoping someone knows how I can adjust my OpenVPN configuration so that I can send and receive text messages while connected to my VPN. My OpenVPN server.config is as follows:
dev tun proto udp port 1194 ca /etc/openvpn/easy-rsa/pki/ca.crt cert /etc/openvpn/easy-rsa/pki/issued/server_2wA4OjM7gfFQzARq.crt key /etc/openvpn/easy-rsa/pki/private/server_2wA4OjM7gfFQzARq.key dh none topology subnet server 10.8.0.0 255.255.255.0 # Set your primary domain name server address for clients #push "dhcp-option DNS 188.8.131.52" #push "dhcp-option DNS 184.108.40.206" # Prevent DNS leaks on Windows push "block-outside-dns" # Override the Client default gateway by using 0.0.0.0/1 and # 220.127.116.11/1 rather than 0.0.0.0/0.
