nginx with multiple subdomains forwarding traffic to wrong server when using VPN
« on: September 22, 2023, 03:10:45 pm »
Hello everyone,

I am running nginx on my OPNsense as a reverse proxy for 4 different services: Vaultwarden password manager, Nextcloud, Grafana and Home Assistant. Two of those services (nextcloud and vaultwarden) should be accessible from everywhere (server bind is set to ::443, 0.0.0.0:443) and the other two (home assistant and grafana) are accessible from within LAN only (server bind is $private_ip:443).

The problem I have is that when I connect to VPN from the outside using Wireguard, I cannot use my password manager because nginx forwards my requests going to vw.subdomain.org to homeassistant.subdomain.org incl. giving me SSL errors (because of the incorrect URL used to access homeassistant.subdomain.org which I didn't want to access).

I have set up my local dns to point to the internal IP address of the firewall running nginx for all of those services I want to proxy.

When I access the service vw.subdomain.org from outside of LAN without connecting to VPN it works, because homeassistant.subdomain.org only binds to $internal_ip:443 and therefore isn't available without VPN?

Any help would be much appreciated!

Cheers

EDIT: After clearing my browser cache it seems to work just fine both from computers within LAN, from devices outside of LAN and from devices connected to VPN from the outside.

Please find my nginx.conf below:
