Hello,
Has anyone used OT scanner centrally to discover OT devices behind a router?
If I use the default setting in "scan targets", I cannot see icmp or other L3/4 protocols being transmitted from the sensors interface (only arp).

HI @Kumppis
The OT scanner in Lansweeper can be used to discover OT devices behind a router. However, you may need to adjust your scan target settings if you only see ARP traffic and not ICMP or other Layer 3/4 protocols. The default settings might not be sufficient for your network configuration, and you may need to use the advanced flow to customize the scan targets and protocol configurations.
To address the issue of not seeing ICMP or other Layer 3/4 protocols, you can follow these steps:
By customizing the protocol configurations, you can ensure the scanner uses the necessary protocols to discover devices behind a router.
