Trusted Firewall

With Virtual I/O Server (VIOS) Version 2.2.1.4 or later, and POWER8® processor-based servers with firmware at level FW740, or later, you can use the Trusted Firewall feature. Trusted Firewall is a feature of the PowerSC™ Editions. You can use the Trusted Firewall feature to provide a virtual firewall that allows network filtering and control within the local server. The virtual firewall improves performance and reduces the consumption of network resources by allowing direct and secure network traffic between logical partitions that are on different VLANs of the same server.

With the Trusted Firewall feature, you can perform LAN routing functions between logical partitions on the same server by using the Security Virtual Machine (SVM) kernel extension. By using the Trusted Firewall feature, logical partitions that are on different virtual LANs of the same server can communicate by using the shared Ethernet adapter (SEA). Trusted Firewall is supported on AIX®, IBM® i, and Linux logical partitions.
