I have an IIS application running on Windows 2012 Server R2 that performs an HTTPS post to a customer site. Moving the application to a supported platform isn't possible at this time.
The customer site recently deprecated "weak" TLS 1.2 ciphers and Windows 2012 doesn't support any of the available ciphers.
I'd like to set up TLS proxy to forward my HTTPS post to the customer site using the strongest ciphers available. Also, this site sits behind a load balancer that performs SSL offloading, so all inbound requests to IIS are already decrypted.
Would this be the correct config to accomplish this:
tlsproxy tunnel add
--in 0.0.0.0:80
--out clientserver.com:443 --out-protocol TLS --out-tls-versions TLS12
?
