Nethor is a free packet analyzer and visualizer designed for working with multiple open Pcap/Pcapng files and more.

This multipane packet analyzer is capable of monitoring and intercepting transmitted network data packets. It can also decode them as well. All features and options are displayed from a modern UI that visualizes nodes and packets through several available options.

Nethor can perform offline analysis of tcpdump (libpcap) and Pcap NG files with the ability to open multiple files but operate them as a single. There is also the ability to display filtering, perform the detailed inspection of several protocols and support Ethernet, IEEE 802.11, and IPv4/6 link types. You can also actively perform live capture (IP only) with all modules/views supporting packet filters and live packets capture.
