Configure Custom Liveliness Probe
Prisma Access for Networks
uses the
concept of an Infrastructure Subnet. The Infrastructure Subnet is
required for services within a given Prisma Access Tenant.When
you create an Infrastructure Subnet, the last usable IP address
provided becomes the following set of services within Prisma Access:
- Captive Portal Redirect IP Address
- Remote Network DNS Proxy IP Address
- Tunnel Monitor IP Address
When the CloudBlade creates
a standard VPN to Prisma Access, the default is to use the Tunnel
Monitor IP Address within the Prisma Access Infrastructure, using a
Liveliness probe. There may be times when a probe may need to be
changed from the default, to monitor additional services external
of Prisma Access for a given business requirement.
