Not all interfaces are available

[bushev]

Hello!

I noticed that I can't capture traffic for some interfaces (like VPN connections). Is it supported?

Output from systeminformation:

[
  {
    "iface": "Ethernet",
    "ip4": "10.190.201.120",
    "ip6": "fe80::4857:7b9f:5352:126e",
    "mac": "50:46:5d:66:5f:ed",
    "internal": false
  },
  {
    "iface": "Beeline Internet", // <--- I want to capture on this interface
    "ip4": "95.29.167.212",
    "ip6": "",
    "mac": "00:00:00:00:00:00",
    "internal": false
  },
  {
    "iface": "Loopback Pseudo-Interface 1",
    "ip4": "127.0.0.1",
    "ip6": "::1",
    "mac": "00:00:00:00:00:00",

  }
]

  }
]

When I'm trying to call findDevice with 95.29.167.212 IP address I gon a null.

Thank you!

Probably a limitation of WinPcap/WinPcap compatibility mode in npcap. Ideally the Windows-specific code should be updated to use npcap's direct API which might help with problems like this.

How can I find all the MAC addresses using this library?
