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 4 Port Vault’s network ports are incremented from right to left

 

The 6 Port Vault’s Network Port Labels increment from right to left

The table below should help to correlate port nomenclature:

Vault ModelPort 6Port 5Port 4Port 3Port 2Port 1
FW1x--OPT2OPT1LANWAN
FW2x----LANWAN
FW4x--OPT2OPT1LANWAN
FW6xOPT4OPT3OPT2OPT1LANWAN
FreeBSD (pfSense) Labeling (in software)em5em4em3em2em1em0
Windows 10Ethernet 3Ethernet 2EthernetEthernet 1

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”.
