Secure Inbound Access for Remote Network Sites
Prisma Access for remote networks allows outbound access
to internet-connected applications. In some cases, your organization
might have a requirement to provide inbound access to an application
or website at a remote site, and provide secure access to that application
for any internet-connected user—not just users who are protected
by Prisma Access. For example:
You host a public-facing custom application or portal
at a remote network site.
You have a lab or staging environment for which you want
to provide secure access.
You have a need to provide access to an application or website to users who are not members of an
organizational domain.
You have IoT devices that require access to an internal asset
management, tracking, or status application.
To do this, create a remote network that allows secure inbound
access. If you require outbound access as well as inbound access
for a remote network site, create to remote networks in the same
location—one for inbound access and one for outbound access.
While this solution can provide access for up to 50,000
concurrent inbound sessions per remote network, Palo Alto Networks
does not recommend using this solution to provide access to a high-volume
application or website.
To make internet-accessible applications available from a remote
network site, you first make a list of the applications to which
you want to provide access, and assign a private IP, port number,
and protocol combination for each application. If you use the same
IP address for multiple applications, the port/protocol combination
must be unique for each application; if you use the same port/protocol
combination for multiple applications, each IP address must be unique.
To begin configuration, you choose how many public IP addresses
you want to associate for the applications. You can specify either
5 or 10 public IP addresses per remote network site. Each public
IP allocation takes bandwidth (units) from your Remote Networks
license, in addition to the bandwidth that you have allocated for
the
compute location associated
to the remote network. 5 IP addresses take 150 Mbps from your remote
network license allocation, and 10 IP addresses take 300 Mbps.
After you choose the number of public IP addresses, you then
enter the application, along with its associated private IP/port
number/protocol combination, for which you want secure inbound access.
You can decide how you want to map your application to the public
IP addresses. By default, Prisma Access assigns the public IP addresses
to the applications you specify, and multiple applications can be
assigned to a single IP address. If you need to map a single application
to a single public IP address, you can select Dedicated
IP during system configuration. You can configure up
to 100 inbound applications for each group of provisioned public
IP addresses (either 5 or 10).
