Hi everyone,
I need to know what is the meaning of the “len” attribute in the firewall log line.
I have firewall log lines like this:
...
Nov 21 11:47:02 83.139.194.xx firewall,info Mik_MASTER: FW_OUT srcnat: in:(none) out:ether4, proto UDP, 10.8.4.183:15840->82.48.142.1
34:37414, len 84
Nov 21 11:47:12 83.139.194.xx firewall,info Mik_MASTER: FW_OUT srcnat: in:(none) out:ether4, proto UDP, 10.8.4.183:15840->71.64.25.13

56:29457, len 131
...
What is the meaning of “len” ? is it the size of the packet in kb? is it the length of the header in bytes?
Thank you, i had no luck reading the manuals
