How to enable PN-DCP/LLDP protocol transfer (siemens PLC discovery)? #1164

Open liveej opened 5 months ago

Accessing the PLC via a remote linux PC using the S7 protocol (TCP) works fine, but it cannot be auto-discovered using the Siemens software (windows). The "-r -E" parameter has been added on both ends. It is using the PN-DCP protocol, is there a way to achieve this via n2n? Bridging seems to be the right answer, but no clue how to operate between windows and linux. wireshark capture: PN-DCP_search.pcap.zip PN-DCP_search
