Hi,
I just setup my home network like this:
- Main router (192.168.1.1): Frtiz.box 7530 set to forward DNS for lan devices to 192.168.1.145
- RockPro64 (19.168.1.145): NAS + pi hole + openvpn + nginx hosting my personal website (say mysite.com) + firewalld
Nginx is configured to only allow requests from 192.168.1.0/24 (lan devices) and 10.0.8.0/24 (vpn devices). It drops other requests. This is working fine.
I use pihole to block ads and also to have some local dns records for mysite.com. So, from my LAN, mysite.com is served locally, never reaching the internet.
I also setup a openvpn server so that I can access mysite.com like if I was at home and this works fine.
My issue is that, when I am connected through openVPN, I have no internet connectivity. I can only browse mysite.com.
I followed the official pihole guide to configure it with openVPN, but when I run pihole -a -i all to have pihole listen to both eth0 and tun0, I lose internet connectivity to all my LAN devices, so currently pihole only listens to eth0. I guess this is the root cause of my issue.
I just double checked and firewalld is correctly configured to allow DNS. HTTP and HTTPS traffic for both LAN and openvpn zones. I also enabled masquerade for openvpn zone.
Does anyone know how to fix this? Or at least provide some hint on what I could try to isolate the issue?
Thanks!
