NIC Port Numbering and Naming


While the Vault's Intel NIC ports are compatible with a wide variety of operating systems (most OS distributions include Intel NIC drivers by default), there can sometimes be confusion about matching external NIC port numbers to internal OS designations for the NIC ports.

External Naming

On the outside, The Vault's network ports are generally labeled one of two way, as can be seen from the below pictures.  The ports are incremented from right to left, and are referred to either by the generic "LANx" numbering, or by their designation in FreeBSD.

The table below should help to correlate port nomenclature. Please keep in mind that our 2.5 GbE NIC devices (V Series, FW4C, VP2420, and VP46XX) will use igc0, igc1, etc instead of igb0, igb1, etc found in our 1GbE devices.

Internal Naming

Depending on which Operating System the Vault is running, the NIC ports are going to be called different things.  In FreeBSD, which pfSense® CE is based on, port numbers are referred to by their driver designation, or "em".
