具有不同源地址的 Nginx 代理

Question

我有一个在职的nginx 配置用于将来自一系列源 IP 的所有请求代理到服务器。我目前设置了 20 个源 IP，配置相当庞大。为了简洁起见，我删除了其他 18 个块。

我想知道是否有更简单的方法可以做到这一点。我需要添加 100 个以上的 IP，这样配置会太大。一定有更好的方法！

澄清：我需要请求来自服务器上配置的 100 个随机 IP 地址之一。目标服务器将看到代理请求来自 100 个地址之一。

HAProxy 或其他替代方案是否更适合这类任务？

简化的 nginx 配置：

# nginx proxies all requests to one of these servers
upstream cluster {
  # one server line for every server block configured below
  server 127.0.0.1:8000;
  server 127.0.0.1:8001;
  # 18 more...  

  least_conn;
  keepalive 16;
}

# one server block for every source ip address configured
server {
  listen 8000;

  location / {
    proxy_pass https://destination;
    # ip address below is one of 20 addresses outgoing requests will bind to
    proxy_bind 10.0.0.1;
  }
}

server {
  listen 8001;

  location / {
    proxy_pass https://destination;
    # ip address below is one of 20 addresses outgoing requests will bind to
    proxy_bind 10.0.0.2;
  }
}

# 18 more server blocks

# redirect all http traffic to https
server {
  listen 80;
  listen [::]:80;

  return 301 https://$host$request_uri;
}

# proxy requests to upstream, which proxies requests to destination
server {
  listen 443 ssl;
  listen [::]:443 ssl;

  location / {
    proxy_pass http://cluster;
    proxy_http_version 1.1;
    proxy_set_header Connection '';
  }
}
