[DNS Problem] Out home can connect to my network but can't surf the Internet

[Brax84 0]

Hi,

i have this setup

My ISP----> Modem (192.168.10.1)---> Raspberry pi4 (192.168.10.3) with PiVpn and Adguardhome

The raspberry connects to airvpn and there is openvpn server to route everything under vpn 
all my devices have a client Openvpn for connect to raspberry and on adguardhome 'I've setup the airvpn dns 10.4.0.1 and 10.5.0.1  
on all client *.ovpn dns server is raspberry (192.168.10.3) for blocks ads etc..

On my network everything works explore network and surfing
Out home my iPhone with client Air DDNS everythings work if my ISP set to me public ip, but  if my ISP set NAT ip can explore network can connect with webssh app to raspberry BUT can't surfing ...there is a dns problem
If I connect with ssh to server airvpn from raspberry everything works even under nat ip , but the performance is clearly lower 

How to solve?
Thanks

P.s Sorry for my bad English

Are you using vanilla OpenVPN or this PiVPN to connect to AirVPN? It's not 100% clear.
Try adding this to your clients' .ovpn:

redirect-gateway bypass-dns

.

Hi,

@OpenSourcerer Connect use vanilla Openvpn , I've my ***.conf in /etc/openvpn folder for automatic start at boot .. PiVPN is only a script method for install and create/manage client but is Openvpn vanilla 

I've test on client  redirect-gateway bypass-dns but same problem
I've test dhcp-option DNS 10.4.0.1 on client but same problem
if on raspberry connect airvpn over ssl no problem work very well

I would set AirVPN DNS for external dns
local DNS for local Network
