Hi all,
I very new to NGINX, but thought that it might be the best tool to
achieve a
reverse proxy ( in the DMZ ) for an internal HTTPS server.
Unfortunately it isn’t working and I get 502 Bad Gateway message if I
check
in the error Log I see :
2014/10/07 17:38:27 [crit] 2606#0: *1 connect() to 172.16.36.155:9999
failed
(13: Permission denied) while connecting to upstream, client:
10.51.44.100,
server: ping0a.cisco.net, request:
“https://172.16.36.155:9999/pingfederate/app/”, host:
“ping0a.cisco.net:9999”
with a tcpdump in the HTTPS server that it is in the internal LAN I
don’t
see any traffic arriving …
I have a split dns schema in my test, and the FQDN name in the internal
HTTPS server is the same as the on e in the DMZ ( ping0a.cisco,.net ).
This is my configuration :
[[email protected] nginx]# more nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local]
“$request”
’
'$status $body_bytes_sent “$http_referer” ’
‘"$http_user_agent" “$http_x_forwarded_for”’;
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
upstream backend {
server 172.16.36.155:9999;
}
include /etc/nginx/conf.d/*.conf;
}
[[email protected] conf.d]# more ping0a_ssl.conf
HTTPS server
server {
listen 9999 default ssl;
index index.php index.html index.htm;
server_name ping0a.cisco.net;
ssl on;
ssl_certificate /etc/pki/tls/certs/IdP.pem;
ssl_certificate_key /etc/pki/tls/private/IdP.key;
ssl_session_timeout 5m;
ssl_protocols SSLv3 TLSv1;
ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+EXP;
ssl_prefer_server_ciphers on;
location / {
proxy_store off;
proxy_pass https://backend;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_ssl_verify off;
}
}
from the hosts in the DMZ where NGINX is installed I can reach the
inetrnal
HTTPS server
[[email protected] conf.d]# wget --no-check-certificate
https://172.16.36.155:9999/pingfederate/app

What is wrong in my configuration ?
Thank you,
