Private networking on IPv6


First thank you for the great service.

I am trying to proxy requests through an nginx app to a redbean web server app. After many hours of struggling and being very close, I think that I can’t bind my redbean process to listen to an IPv6 address.

I have also posted an issue in their github account to see if that would be actually possible (redbean listen ipv6 address · Issue #1077 · jart/cosmopolitan · GitHub).

Is there anything else I can do to work around this issue?

Thank you very much in advance.

Could running something like a socks5 proxy that sits in front of the web server work?

Billy, thanks for answering.

I have never used socks5 proxy before and I was a bit intimidated by the docs. I set up the web machine to also run a nginx proxy through supervisord.

server {
    listen 8080;
    listen [::]:8080;

    location / {

If I send a request from the internet to the web server ( with ipv4) it does work correctly, but when I try to connect through the proxy app (app.flycast with ipv6) I get an Connection reset by peer error:

2024-01-10T09:16:04.832 app[91857e76f5e708] sea [info] 2024/01/10 09:16:04 [error] 311#311: *41 recv() failed (104: Connection reset by peer) while reading response header from upstream, client:, server: ~^(?<subdomain>.+)\.kabano\.com$, request: "GET / HTTP/1.1", upstream: "http://[fdaa:4:f834:0:1::6]:8080/", host: ""

I have figured it.

I had to also configure a service for tcp on the same port in the toml file:

  internal_port = 8080
  auto_start_machines = true
  auto_stop_machines = true
  min_machines_running = 0
  processes = ["app"]

  internal_port = 8080
  protocol = "tcp"

    port = 8080
  	handlers = ["http"]
