Secure Traffic Across Linux hosts

To secure your workloads, more than one instance of the VM-Series firewalls can be deployed on a Linux host. If, for example, you want to isolate traffic for separate departments or customers, you can use VLAN tags
to logically isolate network traffic and route it to the appropriate VM-Series firewall. In the following example, one Linux host hosts the VM-Series firewalls for two customers, Customer A and Customer B, and the workload for Customer B is spread across two servers. In order to isolate traffic and direct it to the VM-Series firewall configured for each customer, VLANs are used.

In another variation of this deployment, a pair of VM-Series firewalls are deployed in a high availability set up. The VM-Series firewalls in the following illustration are deployed on a Linux server with SR-IOV capable adapters. With SR-IOV, a single Ethernet port (physical function) can be split into multiple virtual functions. Each virtual function attached to the VM-Series firewall is configured as a Layer 3 interface. The active peer in the HA pair secures traffic that is routed to it from guests that are deployed on a different Linux server.
