This file documents my troubleshooting methodology for configuring nginx to reverse proxy https traffic, and reverse proxy non https traffic on tcp/443.
|
|
|
|
## Context
|
|
I have an OpenVPN server set up on a Raspberry Pi (`192.168.0.2`) listening on TCP/443 so that it's able to function on most networks. There are enough clients configured that I do not want to remake the server, then update config files for all the clients, and so on.
|
|
|
|
I have a Debian VM running on `192.168.0.6` that runs an "nginx hub" that I'd like to proxy all web-ish traffic out of my network with. It's currently handling at least one http(s) service running from that same VM, and will probably handle more.
|
|
|
|
Given I only have one external IP, I want the ability to handle both OpenVPN traffic and https traffic on port TCP/443. I know it's possible to reverse proxy raw t

|
|
Right now, it appears that I can't do that with one IP because that would require two separate nginx components listening on the same port, or that's what I ascertained from the logs.
|
|
|
|
I modified `/etc/nginx/nginx.conf` to include this block underneath the `http` block:
|
|
```nginx
|
|
stream {
|
|
server {
|
|
listen 443;
|
|
proxy_pass 192.168.0.2:443;
|
|
}
|
|
}
|
|
```
|
|
|
|
When trying to start with that change applied, I got the error:
|
|
```
|
|
nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use)
|
|
```
