Management Interface

Management Interface not only provide Web Interface & SSH access to perform configuration & monitoring tasks for PA-VM, but also need to have Internet access to receive the latest update from Pala Alto Network.


3 x Layer 3 interfaces are created

  • ethernet 1/1 – (untrust)
  • ethernet 1/2 – (trust)
  • ethernet 1/3 – (DMZ)

Virtual Router

**Each Layer 3 Ethernet, loopback, VLAN, and tunnel interface defined on the Firewall must be associated with a virtual router. **

Default Route is configured in Static Routes


A security zone is a group of one or more physical or virtual firewall interfaces and the network segments connected to the zone’s interfaces. You control protection for each zone individually so that each zone receives the specific protections it needs.

NAT Policies for Internet Access

The following 2 x NAT Policies are created

  • Out-NAT-LAN – Allow Trust to Untrust for LAN IP – to access Internet by translating to Untrust Interface IP
  • Out-NAT-DMZ – Allow DMZ to Untrust for LAN IP – to access Internet by translating to Untrust Interface IP

Security Policies

The following 2 x Security Policies are created

  • TrustToUntrust – Allow Trust & DMZ Zone to have full access to Untrust Zone (Internet)
  • TrustToDMZ – Allow full access from Trust to DMZ Zone

Machines from Trust Zone ( and Servers from DMZ Zone ( should have full Internet access now
