      Hi all,

      I am new to PFSense - have been playing around with it on my home network a bit to get a better feel for it and hopefully use in production in the future.

      Probably the millionth post about MITM HTTPS, but most other posts assume that pfsense is your firewall….

      I have been struggling with Squid and transparent proxy for SSL. Transparent proxy works fine on HTTP, but as soon as I enable HTTPS - service wont start with error```
      Bungled /usr/local/etc/squid/squid.conf line 6: https_port 127.0.0.1:3129 intercept

      
I am using ACME certificates and have successfully created the certificates needed for my domains.

This is how I have my network configured:

Unifi Security Gateway - Router, DHCP, Firewall, VLAN
PFSense ( - Firewall off entirely, WAN and LAN interface bridged, DNS Forwarder, DHCP Relay

DHCP: Gateway and DNS server set to PFSense box.

Can anyone shed some light on why this wont work?

          Looking at my squid.conf file with Enable SSL filtering, I'm seeing a lot more content after the word "intercept."

          https_port 127.0.0.1:3129 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=10MB cert=/usr/local/etc/squid/serverkey.pem capath=/usr/local/share/certs

          Are you using the GUI to configure squid?

              You CANNOT use ACME cert!!! You need your own cert. authority!!!
