Using Sentora to forward HTTP/S traffic to another server

[RobbGG]

After some more searching and playing I've finally managed to get it working. I'll leave an explanation here in case anyone else needs it.

Firstly my server needed libapache2-mod-proxy-html to be overhauled. Then I needed to generate SSL certs for both my pritunl server (automatically done and built into the system) and for mt Sentora server (using certbot). I was then able to set up SSL forwarding using the following entry into my virtual hosts file. This was done through Admin -> module config -> Apache -> Override virtual host setting which also requires moving the last </VirtualHost> from the end of this snippet to the start (so it fits in with the Sentora automation).

Code:

<VirtualHost *:80>     ServerName pritunl.my.domain     ProxyRequests Off     <Proxy *>         Order deny,allow         Allow from all     </Proxy>     ProxyPass / http://172.16.1.24:80/     ProxyPassReverse / http://172.16.1.24:80/     <Location />         Order allow,deny         Allow from all     </Location> </VirtualHost> <VirtualHost *:443>     ServerName pritunl.my.domain     SSLEngine On     SSLProtocol ALL -SSLv2 -SSLv3     SSLHonorCipherOrder On     SSLCipherSuite ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS     SSLCertificateFile /etc/letsencrypt/live/pritunl.my.domain/cert.pem     SSLCertificateKeyFile /etc/letsencrypt/live/pritunl.my.domain/privkey.pem     SSLCertificateChainFile /etc/letsencrypt/live/pritunl.my.domain/chain.pem      # Keeping bellow for future upgrades. # Requires Apache >= 2.4     SSLCompression off          SSLProxyEngine On     ProxyRequests Off     ProxyPreserveHost On     ProxyHTMLInterp On     ProxyHTMLExtended On     ProxyHTMLURLMap (.*)172.16.1.24(.*) https://pritunl.my.domain$2 [Rin]     ProxyPass / https://172.16.1.24/     ProxyPassReverse / https://172.16.1.24/ </VirtualHost>
