Sure, it works. Is it clear for you why? :)

Hi Claudio,
What happens if you Try client = no for proxy1 and client = yes for proxy2?

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 = yesaccept = = localhost:54323CAfile = sca.server1.crt.pem;verify = 2
[proxy2]client = noaccept = localhost:54323connect = 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 youClaudio
