>Description:
netstat -ibn is reporting traffic which should originate from a jailed IP address as though they are otiginating from the host IP address. Inbound packets/bytes are correctly associated with the jailed IP, only the output packets are reported incorrectly.
>How-To-Repeat:
Create a jail, ping the jailed IP address, then use
netstat -ibn
on the host machine. The jailed IP address output packets and bytes will remain at zero
