There are three configurable ways to do TLS termination with secure routes in OCP; namely edge, re-encryption, and passthrough. Both also use scp and ssh commands to upload custom TLS/SSL certificates to F5 BIG-IP ... With passthrough termination, encrypted traffic is sent straight to the destination without the router providing TLS termination. The diagram below gives an outline of the setup: * SSL Termination When the load balancer is responible for decrypting SSL traffic before passing request on, it’s referred to as “SSL Termination”. Load balancer will send the request that passes the firewall to different webservers. All firewall states are synced between them. * SSL Pass-Through * To have backend servers, rather than HAProxy, handle the SSL connection. A good way to host many services on a single IPv4 address is to employ a reverse proxy, I use NGINX for that purpose. Comments.
