Packet Capture
Live capture on one adapter or all of them, with filters you can change mid-run.
You need to see whether the traffic is arriving at all, and from whom.

Address, port and protocol filters are compiled to BPF and applied by the driver, so the filtering happens before the packets reach the app. Application and keyword filters are matched after decoding and can be changed while the capture runs.
Ethernet, IPv4, IPv6, ARP, TCP, UDP and ICMP are decoded to a one-line summary each, common applications are identified, and DNS queries and HTTP request lines are summarised.
What you walk away with
- Confirmation that traffic is or is not arriving on an interface
- A quick read on which hosts and applications are talking
- DNS and HTTP request visibility without a full analyser
Where it stops
Stated here rather than discovered on site.
- Needs Npcap, and administrator rights to see traffic at all.
- No packet detail tree, no hex view, no follow-stream, and no reading or writing of pcap files. Decoding stops at a one-line summary.
- This is a visibility check. For real trace analysis, use Wireshark — it is free and it is better at this.
