Remote Networks: IP Address Changes Related To Bandwidth Allocation
Learn about how IP addresses change for legacy remote
networks that allocate bandwidth by location.

This section applies if you have a legacy Prisma Access deployment that allocates bandwidth by
location. Any new deployments allocate bandwidth by compute location; to learn about how
Prisma Access allocates those IP addresses, see Remote Networks: IPSec Termination Nodes and Service IP Addresses.
IP addresses for remote network connections are unique, not shared,
and dedicated to your Prisma Access deployment. These IP addresses
do not change after Prisma Access creates them as part of remote
network onboarding, and the IP addresses persist after an upgrade.
However, take care when increasing the bandwidth of an existing
connection, because the IP address of a remote network can change
if that increase causes the bandwidth in a location to exceed 500
Mbps.
In addition, egress IP addresses can change if Prisma Access creates a new Prisma Access compute
location and you decide to use this new compute location with locations you have
already onboarded.
These bandwidth guidelines apply only when you upgrade an existing connection. A single remote
network connection, even a 1000 Mbps (Preview) connection, always receives a single Service IP Address,
regardless of its size.
The 1000 Mbps bandwidth option is in preview mode. The
throughput during preview is delivered on a best-effort basis and
the actual performance will vary depending upon the traffic mix.
The following example shows three remote network connections
in the same location, each with a bandwidth of 150 Mbps. Since the
total bandwidth is 500 Mbps, Prisma Access assigns a single IP address
for all connections in the location.
The following example shows the bandwidth of remote network connection A being increased from 150
Mbps to 300 Mbps. Since the total bandwidth of all connections is now more than 500
Mbps, Prisma Access assigns a new service IP
address for the
connection with the additional bandwidth. The other service IP addresses remain unchanged.
Conversely, given four remote networks with a bandwidth of 100 Mbps, if you increase the
bandwidth of one of the remote networks to 100 Mbps, the Service IP Address
of that remote network does not change because the total bandwidth is now 500 Mbps.
If you reduce the bandwidth of a remote network connection, the Service IP
Address does not change.
To find the service IP addresses in Panorama, select tab and click the Remote Networks radio button to
display the Service IP
Address for the remote networks, or use the API
script.
