The availability of proxy configuration options is based on the proxy type. You must first configure a DNS proxy object to configure a proxy.

Proxy Fields	Description
Proxy Enablement
Proxy Type	Select the type of proxy you want to use. None—The proxy is deactivated. Explicit—Configure the proxy so that the request contains the destination IP address of the configured proxy and the client browser sends requests to the proxy directly. Transparent—Configure the proxy so that the request contains the destination IP address of the web server and the client browser is redirected to the proxy. Transparent Proxy requires a specific Destination NAT (DNAT) policy rule to successfully configure the web proxy. Refer to the PAN-OS Networking Administrator’s Guide documentation for the complete procedure. Palo Alto Networks Service Proxy—Configure the proxy to forward communications from firewalls in the downstream network to destinations in the upstream network. The firewall can act as a single proxy or as one in a series of proxies. This proxy mode is supported on PA-1400, PA-3400, VM-300, VM-500, and VM-700 firewalls running PAN-OS 11.0.1-h2 or later. To enable a firewall to support this proxy type and display it as an option here, enter the following CLI command and then reboot your firewall: set system setting paloalto-networks-service-proxy on
Proxy Configuration
Connect Timeout	Specify (in seconds) how long the proxy waits for a response from the web server. The range is 1–60 seconds and the default is 5 seconds. If there is no response after the specified amount of time has elapsed, the proxy closes the connection.
Listening Interface `Explicit Proxy only`	Specify the Layer 3 (L3) interface where the firewall checks for traffic to reroute to the proxy.
Upstream Interface	Select the upstream interface. If you are using a loopback interface, specify that interface as the Upstream Interface.
Proxy IP	Specify the IP address of the interface where the firewall should check for traffic to reroute to the proxy (listening interface).
DNS Proxy	Select the DNS proxy object you want to use for the proxy connection.
Check domain in CONNECT & SNI are the same `Explicit Proxy only`	Enable this option to prevent domain fronting attacks caused by specifying different domains between the CONNECT request and the Server Name Indication (SNI) field in the HTTP header.
Authentication service type `Explicit Proxy only`	Select the type of service you want to use to authenticate users. SAML/CAS—Use a SAML 2.0 based authentication service or the authentication service available in the Cloud Identity Engine. This option requires Prisma Access, the Cloud Services 3.2.1 plugin, and the add-on web proxy license. Kerberos Single Sign On—Use the Kerberos Single Sign-On Service to authenticate users. This option requires Panorama, a web proxy license, and an authentication profile that uses Kerberos Single Sign-On Service on the firewall. No authentication—Exempt all explicit web proxy traffic from authentication. If you select this option, all proxy connections are unauthenticated and the firewall or Panorama does not create logs for authentication events.
Authentication Profile `Explicit Proxy only`	Select the authentication profile you want to use for the Authentication service type you selected for the previous option.
