I sniffing udp communication with 2 instance of wireshark , 1: 2.0.0 2: 2.2.1 .
In version 2.0.0 I get valid udp.checksum , but with 2.2.1 I always get udp checksum = 0000 .
Why is that? those wireshark sniffing the same packets.
The real problem is , when I save the same packet and play this packet via 'playcap' or another tools that only play pcap file , so if I saved it with in wireshark 2.0.0 I get a response from the pc , but if I saved it via 2.2.1 I not get a response from the pc.
That same packet data , but it seem that wireshak damadge it , is that make sense?
