[stunnel-users] How to use stunnel as a HTTPS to HTTPS reverse proxy

[Claudio Beretta]

I'd like Stunnel to act as a reverse proxy that accepts TLS 1.0 and TLS 1.2
for https://example.com and then forwards the traffic to https://example.net,
another web server that only accepts TLS 1.2
browser --TLS 1.0 or 1.2--> Stunnel --TLS 1.2--> Web App

The browser should have no idea that example.net even exists (only
example.com certificate will be presented to the browser).
Is this something Stunnel can do?


This is what I got so far:

cert = example.com.pem
;stunnel.pem

[proxy1]
client = yes
accept = 10.100.4.179:443
connect = localhost:54323
CAfile = sca.server1.crt.pem
;verify = 2

[proxy2]
client = no
accept = localhost:54323
connect = example.net:443
;CAfile = SymantecClass3EVSSLCA-G3.pem

example.com.pem contains the public and decrypted private key for
example.com
sca.server1.crt.pem contains the intermediate and root certificates of the
CA that issues the example.com.pem certificate

It partially works: the browser shows example.com in the address bad and
the content of example.net, but the certificate that is returned is from
example.net

What am I doing wrong?
Or do you have other recommendations to get something like this working on
Windows Server 2008 R2? (IIS + Application Request Routing + URL Rewrite
won't work: TLS1.2 is not properly supported)

Thank you
Claudio
