Re: [opensuse] What is the meaning of these firewall log entries?

ID=3128 PROTO=UDP SPT=6666 DPT=6666 LEN=323 ]

But that is not possible. I have explicitly open "udp,6666" on both machines:

FW_TRUSTED_NETS="192.168.1.14,udp,syslog 192.168.1.14,tcp,514
192.168.1.14,udp,6666 192.168.1.14,icmp"

and conversely on the other machine.


In fact, "netcat -u 192.168.1.15 6666" succeeds to send text to the other
machine.


The strange thing is that it stops working after some time (hours?), and I have
to restart on the listener:

netcat -u -l 6666 | tee -a remote_log


Apparently, it happens when I stop the sender.
