Dear all, I'm using PPPOE connection and how to activate Suricata IPS mode?

Hi there,

What issue are you facing in enabling it?

Also, do you plan to monitor the WAN-side or the LAN-side?

Suricata IPS mode on PPPOE is not permitted.

Did you take a look at this topic?

I tried read the posts but still not understand it.

1. Configure the WAN interface as none (IPv4 Configuration Type none)
2. Add a new OPT interface with the PPPoE configuration just like it was a WAN PPPoE.
3. Configure Suricata as IPS on WAN.
