Hi! Thank's for solution.
I'm doing a follow up to see any more error so far, still watching this log :
Tue Apr 17 11:29:31 2018((GMT-0300)) [FVS336GV3][Kernel][KERNEL] xt_TCPMSS: bad length (209 bytes)
Tue Apr 17 11:25:06 2018((GMT-0300)) [FVS336GV3][Kernel][KERNEL] xt_TCPMSS: bad length (209 bytes)
Tue Apr 17 08:34:25 2018((GMT-0300)) [FVS336GV3][Kernel][KERNEL] xt_TCPMSS: bad length (552 bytes)
Mon Apr 16 18:24:19 2018((GMT-0300)) [FVS336GV3][Kernel][KERNEL] xt_TCPMSS: bad length (324 bytes)As I have mentioned from my previous response, there might be possible that there is a DDOS attack. It is similar to the concern posted on the forum thread here. The logs states that the firewall received an improperly formatted TCP packet. It might be a hacker probing the firewall to see if it can breach the firewall's security. The firewall handles this correctly in which it discards the packet without any harm.
