HTTPS transparent proxy feature not working

[Igal]

Hi,

I'm trying to set up fiddler as a transparent proxy for HTTP(S)

Traffic Flow:  WindowsHOST ---> Ubuntu (IPtables) ----> fiddler (listen on 8888 )  --> Internet

I have enabled HTTPS decryption + allow remote computer + prefs set fiddler.network.https.SetCNFromSNI true + added fiddler root cert to WindowsHOST

 HTTP working fine, however HTTPS not working...

All traffic routed correctly to fiddler using DNAT.

In addition I tested the same setup replaced fiddler with burp suite and all working fine, including HTTPS interception, I would love to use fiddler instead :)

I would really appreciate any help,

Thanks.

Hello,

What do you mean it is not working? What kind of client do you have running on the windows machine? What error message are you getting there? Does anything show up in Fiddler for HTTPS traffic at all? What is there in Fiddler Log tab?
