Посмотреть что отдаёт апач без проксирования можно вот так:
http://1.dair.cz8.ru:8083/twiki/bin/view/

конфиг nginx прост до безобразия:
user  www www;
worker_processes  2;

error_log  /var/log/nginx-error.log error;
pid        /var/run/nginx.pid;

events {
    worker_connections  2000;
    use kqueue;
}

http {
    include       mime.types;
    default_type  text/html;
    sendfile  on;
    access_log  off;
    large_client_header_buffers 32 16k;
    client_header_buffer_size   2k;
    client_header_timeout  10m;
    client_body_timeout    60m;
    ignore_invalid_headers off;
    server_names_hash_bucket_size 128;

    server {
        include listen.conf;
        location / {
            access_log  off;
            proxy_pass  http://127.0.0.1:80/;

            client_max_body_size       10m;
            client_body_buffer_size    512k;

            proxy_connect_timeout      600;
            proxy_send_timeout         300;
            proxy_read_timeout         300;
            proxy_send_lowat           8191;

            proxy_redirect     off;
            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

            proxy_buffer_size          4k;

            proxy_temp_file_write_size 64k;

            proxy_temp_path            /tmp/nginx;
        }
    }
}

Что я делаю не так?
