@gertjan said in Squid HTTPS Interception not working?:
For https port 3129 could be used I guess - example : https://www.microlinux.fr/squid-https-centos-7/ (Squid version 3.5).
True, the official doc is hard to read.
Well, in order to get this working, I have the SSL interception running on port 3129 and the main proxy on 3128.
Pointing clients at 3129 for HTTPS results in no connectivity. However upon just telling clients to use 3128 for HTTP and HTTPS, I can see HTTPS Man in the middle working and the certificates are being issued by my CA as expected.
This suggests that PfSense+Squid is doing some sort of redirection internally to 3129 for HTTPS, or the seperate port setting for HTTPS does nothing, and it just listens on 3128 full stop.
