Problem:After setting up a nginx reverse proxy for a ADFS 3.0, instead of MS WAP, it was coming back connection reset by peer. When browsing to the site via IP or anything other than the original hostname it would return this error.
Reverse Proxying ADFS with Nginx
I have similar application which doesn't use reverse-proxy, and there it works flawlessly. My question here is how to force WIF to understand that redirect happens within the same application? Or any other advice to make it working.
For more complex and hybrid environments, the F5 BIG-IP system is a full proxy that can be deployed as a full reverse proxy server capable of intercepting, inspecting, and interacting with requests and responses. This includes the basic functions of load balancing and web performance optimization, as well as more advanced traffic management services such as application layer security, web acceleration, page routing and secure remote access.
The default configuration file looks like a prime candidate to host the configuration that we're looking for. If you inspect the /etc/nginx/sites-enabled/default file by using cat /etc/nginx/sites-enabled/default, you would see that the default server directive is put within the following code.
that particular section is geared for a proxy with nginx, but the main gitlab.rb changes ensure that the bundled nginx is disabled. Also, you need to look at what type of configuration you are doing between your reverse proxy and Gitlab.
What these scenarios have in common is that they consist of loosely coupled components that are seamlessly hidden to the end user behind a common interface. Often, a reverse proxy serves content from one single entry domain but retrieves the content from different origins. In the example in Figure 1 (below) we want to address one specific domain name, and depending on the path prefix, we retrieve the content from an on-premises webserver, from a webserver running on Amazon Elastic Cloud Compute (EC2), or from Amazon S3 Static Hosting, in the figure represented by the prefixes /hotels, /pets, and /cars, respectively. If we forward the path to the webserver without the path prefix, the component would not know what prefix it is run under and the prefix could be changed any time without impacting the component, thus making the component context-unaware.
The traditional approach would be to run a reverse proxy tier with rewrite rules to different origins. In this post we look into managed alternatives in AWS that take away the heavy lifting of running and scaling the proxy infrastructure.
With AWS Amplify Console, Amazon API Gateway, and Amazon CloudFront, we have seen three approaches to implement a reverse proxy pattern using managed services from AWS. The easiest approach to start with is AWS Amplify Console. If you run into more complex scenarios consider API Gateway. For most flexibility and when data traffic cost becomes a factor look into Amazon CloudFront with Lambda@Edge.
1) If I can configure either apache or nginx to " maintains a 1:1 connection affinity (a persistent connection) with Kestrel.", how to not use a proxy, not use negotiate, or if "An alternative to Windows Authentication in environments where proxies and load balancers are used is Active Directory Federated Services (ADFS) with OpenID Connect (OIDC)." is an option.
typically when authentication is done by the reverse proxy (say in your example), the user credentials are passed to app via a x-forward headers. you'd configure this with add module to the proxy that supports ad auth.
Hi,i am new the forum. So thanks in advanced for your help!I have successfully build an nextcloud instance on an ubuntu 20 server with ssl enabled and ADFS authentication working.But i have to get the ADFS SAML authentication think workting on a Nextcloud Docker instance that is running behind an nxing reverse proxy.
The nextcloud is working. That is not the issue. I am able to open the website with my company ssl certificate that was created for the nginx server. But the SAML configuration is not working. I have no idea how to fix that.I think the issue is, that the container inside is not using https. In the logfile of my adfs server i see that the website that is returning the error begins with http.
I had the same issue on my ubuntu box. But after changing the default redirection for the apache to https, adfs was working. I was able to download the xml file with the correct settings.I am working on this for days now without any result. So i was hoping to get some sort of ideas from the forum.
By structuring your system this way, you can put all your sensitive material on the internal web server, and protect everything through an authenticating reverse proxy. For even more security, the internal web server could be placed on a private Virtual Private Cloud, with absolutely no access from the outside, except through the proxy.
Protecting a site using an authenticating reverse proxy is very easy with Keycloak. Keycloak provides you with all the identity and access management tools you need, and the lua-resty-openidc library can be used to configure the proxy.
The standard method for validating access tokens with an IdP is called token introspection. Nginx acts as an OAuth 2.0 Relying Party, sending access tokens to the IdP for validation i.e. token introspection, and only proxying requests that pass the validation process.
This module is shipped with nginx, but requires enabling when you compile nginx. When you download the nginx source and compile, just include the --with-http_auth_request_module flag along with any others that you use.
However, it is possible to forward calls through a proxy such as IFS TouchApps Server or a similar generic 3pp reverse proxy with filtering capabilities (e.g. Netscaler, IIS, Apache, NginX). Caution should always be taken when making sensitive systems accessible from the Internet. Depending on which functionality need to be accessed from the Internet, only the required requests should be forwarded to the backend servers. Some functionality should never be accessible from the internet, such as the Middleware Server Admin Console and all endpoints secured only by HTTP Basic authentication. IFS consider well known and maintained proxies safe. The forward filtering and black/white listed IP addresses are considered a reliable restriction. The Admin Console and HTTP Basic authenticated integrations may therefore be forwarded to using a proxy if explicit source IP addresses are white listed and all other access is blocked.
The TouchApp Server (TAS) is a proxy in it self and often installed on a separate server, but it can be configured to be accessed from the same reverse proxy as IFS Applications, but with a separate unique FQDN, port and certificate.
The proxy must be a reverse-proxy i.e. not connecting external requests to the MWS webserver, but terminate the internet connection in the proxy and create a new connection towards the MWS on the intranet.
The proxy must send a host-header to MWS webserver containing the correct Proxy URL otherwise the requests will be blocked by the webserver.
The IEE client uses WebSocket notifications, so a proxy needs to be WebSocket compliant and support upgrade of http protocol to WebSocket protocol.
The http header responces from the proxy must always set the host as the proxy url. e.g. "proxy_set_header host $http_host"
Proxy should not have SNI support enabled.
SSL 2.0, SSL 3.0 and TLSv1 are considered insecure and should be disallowed.
Test proxy with a tool like and make sure you get a A+ rating, otherwise don't expose the proxy to the internet.
I have a NGINX box inside the network which I currently use for reverse proxy for various subdomains as I have a number of web servers. This is a fairly basic setup where all HTTPS traffic hits the nginx box which then determines which web server to pass it onto based on the domain name in the URL.
I'm replacing my old firewall with a new T80. If I want to migrate the old NGINX box to the new T80 and use it for reverse proxy do I use the HTTPS Proxy or the Reverse Proxy function on the T80. I don't have a need for Access Portal and I have Basic Security Suite. So will I still be able to reverse proxy multiple domain URLs to various servers behind the T80 and if so which function should I use? These are mainly for application APIs from client sites so not really remote users but remote applications. Thanks.
Hello the moodle community,For a university project I must deploy a static website and a moodle instance (i have acces to one server: Ubuntu 16.04, php7.0, mysql5.7).For this purpose i have stored the static website on the VPS host and I use a docker container for the moodle instance.To make those two thing public, I use a nginx proxy with the following config in the server block:
Did you try the same docker env without using the rev proxy e.g. in a testing env just to be sure that your issue is actually due to the rev proxy?At first glance, the nginx proxy settings look correct.
In this way, you can enable OpenID Connect (OIDC) or AzureAD authentication with NGINX and Vouch Proxy. You don't need to implement the login mechanism for each application running behind the NGINX reverse proxy. In addition, user management can be completed on the ID management provider side (not within each application).
NGINX logs are located in /var/log/nginx/Vouch Proxy logs are available with the following command.To get more logs (debug log) for Vouch Proxy, set vouch.jwt.logLevel to "debug" in config.yml.
It's okay, I just wanted to understand.Exposing vCenter directly to the internet is not a good idea. Up to my understanding:vCenter is designed to run as an internal service, so you always have one FQDN for the vCenter. (let's say: internal.vcenter.com)Internal api calls within the vCenter and it's sub component will use the internal.vcenter.com fqdn. What you can try is putting a redirect http redirect on the reverse proxy for everything pointing to public.vcenter.com it should be redirected to internal.vcenter.comThat being said, I don't remember the exact setting 2ff7e9595c
