tPacketCapture captures the IPv4 TCP/UDP communication.
So ICMP packets, such as ping, are not recorded.
Informations of Deta Link Layer are not captured because tPacketCapture uses Vpn for packet capturing.
However, some softwares are failed to load the PCAP file that not contains information of Data Link Layer, so tPacketCapture writes the fixd value to a capturing data as ethernet header.

Our users sometimes report this problem. We investigated the problem, it seems that the cause is in OS. So, we think it is difficult to solve this problem. Instead, We will suggest an idea to disconnect VPN connection without using key icon. The idea is “Create Dummy VPN Setting”. When tPacketCapture is monitoring network, select dummy VPN setting to connect dummy VPN. It makes OS to disconnect current VPN connection, and try to connect to dummy VPN. Of course OS can not connect to dummy VPN, so OS does not have any VPN connections.
Please try the tPacketCapture(Free) before downloading the tPacketCapture Pro(Paid).
