Re: Apache as a Mutual SSL enabled Forward Proxy

[eranda rajapaksha <erandacr@xxxxxxxxx>]

I was able to get it work by setting the SSL artifacts at the clients end but not in the Apache server. I thought SSL is applied at Server to Apache and Apache to Client is non-encrypted. So I have to place the certs and keys at the Apache Server. 

Is it that Apache forward proxy doing just a passthrough and connection is encrypted from Client to Server?

Thanks,

Eranda

Never heard of mutual ssl enabled before. What is the use case for this setup?

Would it work for having Nginx SSL offloading to Apache? Any docs?

Your next thing to test, from a vanilla/completely reset browser, would be

to load up these corresponding cert+key and ca chain files into that blank

slate, and ensure that these credentials actually work against your backend;

  SSLProxyMachineCertificateFile D:\sys-projects\aaa\Apache24\Apache24\security\key-client.pem

  SSLProxyCACertificateFile D:\sys-projects\aaa\Apache24\Apache24\security\server.pem

Also drop your proxy server's log level to debug and discover what it has to say.

Hi all,

Im trying to configure Apache http server as a forward proxy with mutual ssl enabled. Following is the setup,

[HTTP client] ----------> [Apache Http Server]----------->[Web Server]

I need to enable Mutual SSL between  Apache Http Server, Web Server. Following is the proxy I have configured. It works fine when connecting other internet web servers.

Listen 3128

 

<VirtualHost *:3128>

  ProxyRequests On

  SSLProxyEngine On

  SSLVerifyClient require

  SSLVerifyDepth  10

  

  SSLProxyMachineCertificateFile D:\sys-projects\aaa\Apache24\Apache24\security\key-client.pem

  SSLProxyCACertificateFile D:\sys-projects\aaa\Apache24\Apache24\security\server.pem

  

</VirtualHost>  

I have tested connecting client directly to the Web server bypassing Apache Forward proxy and it works fine. But when it tries to connect through Apache server I'm getting following error on clients end,

java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 403 Proxy Error"

Even if I just enable one way SSL, the behavior is the same. Am I not importing the Server cert correctly into Apache? Or is there other configuration issue in my setup.

Please help me on this.

Thanks,
