Transparent Proxy with nat

  • Good morning,
    I've the following problem:
    I have a Pfsense appliance that manage my network. I also have a Proxy VM based on Squid.
    I would like to forward all http and https requests from my client to the the proxy port. I've attempted to create a NAT rules in Port Forwarding section but it doesn't work.
    Is there any way to use an external proxy (not Pfsense itself in transparent mode ssl?
    Thanks in advice.
    Best regards,
