Thomas-Krenn offers several server systems optimized for OPNsense. In this overview you will find the assignment of the interface names (igb, ix, em, ...) to the respective network ports.

Important note: Care should be taken when naming and assigning interfaces to rack servers. Please always consider your individual configuration. If, for example, your server has onboard Broadcom interfaces (e.g. bnxtX) and an Intel-based network card (e.g. igbX) is also installed, in our experience OPNsense will set the igbX (or igcX) interface (of the added card) for the LAN and WAN interfaces during installation. It can also happen that the numbering of the network interfaces does not start with igb0 and igb1 (if there are several) for the onboard interfaces, because an additional Intel-based network card is assigned as igb0. For this reason, the illustrations of the rack servers show the names of the onboard interfaces without additionally installed network cards.

Hints

  1. 1.00 1.01 1.02 1.03 1.04 1.05 1.06 1.07 1.08 1.09 1.10 1.11 1.12 1.13 1.14 If additional network cards are used, the assignment of the interface names may change. For example, on a RI1102H/RI1104H the igb designations are shifted by 2 digits if an Intel I350-T2 is installed. This also applies to the installation of an X710-DA2 for example in the RI1102D-F (version 2.1), then the ixl-designations are shifted by 2 digits. This also applies to bnxt interfaces if, for example, a Broadcom P225p is installed. The assignment of the interface designations starts with the additional cards.
  2. The arrangement of the interfaces (igb0 seen from the back at the bottom left and igb1 seen from the back at the top left) also applies to the servers with the Asus P11C-M/4L motherboard (4x 1 Gbit/s LAN (RJ-45)): 1HE Intel Single-CPU RI1102H-XE and 1HE Intel Single-CPU RI1104H-XE and 2HE Intel Single-CPU RI1208-XE
