Basic Reassembly

ProtocolStack stack = new ProtocolStack();
stack.getProtocol(IpProtocol.class).enableReassembly(true);

try (NetPcap pcap = NetPcap.openOffline("fragments.pcap", stack)) {
    Ip4 ip = new Ip4();
    pcap.loop(-1, packet -> {
        if (packet.hasHeader(ip)) {
            // Arrives reassembled
            System.out.println("Reassembled: " + ip.totalLen());
        }
    });
}

Tunnel Decapsulation

stack.setProtocol(new VlanProtocol()).decap();
stack.setProtocol(new GreProtocol()).decap();

// Downstream sees clean inner traffic
