Question

How to setup NGINX reverse proxy for proxying multiple subdomains with ipv4 and ipv6

Hello,

I asked nearly any tutorial about an answer for my specific question. I also asked in serveral communities for an answer. The only answer I got was: “we do not use ipv6 and NGINX proxy manager. That’s quite frustrating…

All of my services are reachable via ip4 as well as ip6. But when I’m setting up NPM for proxying them only ip4 is working… There has to be a way to proxy the ip4 and ip6 addresses for the same subdomain…

Also, how to enable TLS1.3 in NPM?

Is there anyone who can answer me that question?

Hi there,

Setting up NGINX for IPv6 is fairly straightforward, although before starting you need to make sure that you’ve actually enabled IPv6 on your Droplet as described here:

https://docs.digitalocean.com/products/networking/ipv6/how-to/enable/

After that you can verify that this is actually enabled with:

ip addr show | grep inet6

After that to and IPv6, inside each Nginx server block, add:

listen 80;
listen [::]:80;

This listens to both IPv4 and IPv6. For more information you can check out the official docs here:

http://nginx.org/en/docs/http/ngx_http_core_module.html#listen

You can do the same thing for port 443 as well.

Regarding your second question, to enable TLS 1.3 by adding it to the ssl_protocols directive in the NGINX server block for port 443:

    ssl_protocols TLSv1.2 TLSv1.3;

After making the chages, test the configuration with sudo nginx -t and if there are no errors, restart NGINX with sudo systemctl restart nginx.

Best,

Bobby
