Choose the

Prisma Access

where you want to support mobile users.

For the best user experience, if you're limiting the number of locations, choose locations that are closest to your end users. If a location isn't available in the country where your mobile users reside, choose a location that is closest to the mobile users.

Configure a proxy auto-configuration (PAC) file for explicit proxy that meets the following requirements.

For your PAC file to work with the GlobalProtect app-based proxy, it cannot exceed 1 MB.
The Proxy statement in the PAC file must use the
Prisma Access
FQDN you configured above.
The PAC file must be configured to bypass 3rd party VPN traffic.

Sample PAC file:

function FindProxyForURL (url, host) {
	/* Bypass localhost and Private IPs * /
	var resolved_ ip = dnsResolve (host) ;
	if (isplainHostName (host) ||
	shExpMatch (host,"* ‚local") ||
    	isInNet (resolved_ip,"10.0.0.0", "255.0.0.0") ||
    	isInNet (resolved ip,"172.16.0.0","255.240.0.0") ||
    	isInNet (resolved_ip,"192.168.0.0","255.255.0.0") ||
    	isInNet (resolved ip, "127.0.0.0", "255.255.255.0" ))
	return "DIRECT";
	/* Bypass Non-HTTP * / 
	if (url.substring (0,4) == "ftp: ")
		return "DIRECT”;
	/* Bypass VPN */
	if (shExpMatch (host, "vpn. acme.com") || shExpMatch (host, "gateway. acme.com" ))
		return "DIRECT";
	/* Bypass Private Apps */ 
	if (shExpMatch (host,"internalapps. acme.com" ) )
		return "DIRECT";
	/* Forward to 
Prisma Access */
	return "PROXY acme-demo.proxy.prismaaccess.com: 8080";}

.

All requests to the proxy are authenticated. However, if you're passing IDP flows through the proxy, then you need to bypass them for the authentication to be successful.

In this example, we're bypassing the GlobalProtect portal and Okta, but please customize these to the IDPs that you use.


Set up the GlobalProtect Portal, authentication, and configure Proxy mode for the GlobalProtect app.
Enable GlobalProtect for mobile users and set up the GlobalProtect portal.
Enable GlobalProtect proxy mode for
Prisma Access
in the GlobalProtect app settings to send internet traffic to the agent-based proxy.
The GlobalProtect connect method doesn't apply in proxy mode as it is always on.
Select

If you're using Strata Cloud Manager, go to

Prisma Access
Setup
GlobalProtect
.
On the
GlobalProtect App
tab, click
Default
to customize the app settings or
Add App Settings
add a new configuration.
Click
Show Advanced Options
and in the
App Configuration
section.
Set
Agent Mode for
Prisma Access
to
Proxy
to instruct the GlobalProtect app to send the internet traffic to the explicit proxy on Prisma Access.
(
Optional
) Configure the local proxy port. The port range is 1024 to 65534 and the default port is 9999. If the default port isn't available, GlobalProtect will try 10 other ports in the range of 9999 to 10009 and use the port that is available. You can also pick your own port number within the range.
(
Optional
) Configure PAC Auto-Configuration (PAC) File URL if you want to push the new PAC URL for the proxy settings to the endpoint. The PAC URL pushes to the endpoint once the user connects. When the user disconnects the GlobalProtect app, the endpoint proxy configurations are automatically disabled and reverting to the previous settings.
(
Optional
) Enable Allow User to Rediscover Network if you want the user to check the portal for any new settings.
(
Optional
) Configure GlobalProtect App Config Refresh Interval (hours). By default, the GlobalProtect client refreshes the cached portal configuration every 24 hours. You can change the refresh interval based on your business requirements.

(
Optional
) Configure the GlobalProtect app in proxy mode in a non-default route network.
(
Optional
) Host a PAC file internally and add the
Prisma Access
explicit proxy FQDN as a proxy in the PAC file.
In the PAC file, forward the IDP URL and
Prisma Access
portal URL to explicit proxy.
On explicit proxy, exclude the IDP and portal URL from the authentication settings. Add the IDP and portal URL to the domain used in the authentication flows.
Set up routes to the explicit proxy FQDN or IP addresses on perimeter devices to allow users to access the internet via the explicit proxy.
(
Optional
) Add DNS records to resolve the
Prisma Access
explicit proxy FQDN to an internal IP address if users can’t resolve public domains in the branch network and add destination NAT for the internal IP address to the explicit proxy FQDN or IP address.
