Hardware and Performance / 2 Transparent firewall bridges on the same PC

« on: June 03, 2021, 01:21:40 pm »

Hi,

The most common setup is Suricata on WAN and Sensei on LAN or vise versa.
Senses's newly introduced l2 transparent bridge mode cannot be implemented on the same bridge with Suricata.
I thought this setup might solve the issue.

1 PC
4 NIC's

NIC1 - WAN1
NIC2 - LAN1
 
Transparent Firewall Bridge 1 (WAN1 & LAN1)

NIC3 - WAN2
NIC4 - LAN2

Transparent Firewall Bridge 2 (WAN2 & LAN2)

Physical (Patch cable) External Bridge (LAN1 & WAN2)

Suricata on Transparent Firewall Bridge 1

Sensei on Transparent Firewall bridge 2.

Can OPNsense handle 2 Transparent Firewall Bridges on the same PC?
