So i will translate in Sudovien You have a trace a mateweather that's seems not on your computer. UFW (your firewall), block some TCP action on a machine or your machine who get enp1s8 as network adaptater Some tips : IN incoming interface OUT outgoing interface MAC hardware address SRC IP address in the source field in the IP header DST IP address in the destination field of the IP header LEN Length of the IP packet TOS originally called Type of service, these days it is the Differentiated Services Code Point TTL Time to live PROTO name of protocol tcp/udp are most common SPT Source port from tcp/udp header DPT Destination port from tcp/udp header DF TCP don't fragment flag SYN TCP Syn Flag ACK TCP Ack flag WINDOW TCP Window SEQ Sequency number Nothing wrong
