They seem to hit the invalid flag a lot, might depend on connection tracking settings, not sure. Mike O'Connor <mike@oeg.com.au> schrieb am Di., 14. Apr. 2020, 21:47:
Hi All
I've been asked to look at a problem with a web filtering system for a business.
Ever since they upgraded from a 6.5.x version to a current long term release of RouterOS the filtering (RST Packets) traffic generated by the filter system has been lost/blocked by the router.
I have pcap files generated by the router showing the RST packets being generated and sent to the client and server of a tcp connection but captures of the inbound and outbound traffic path do not show these RST packets.
rp-filter is turned off, ip connection traffic how been tried on and off.
I found someone else asking this question https://forum.mikrotik.com/viewtopic.php?t=149084 the single reply was from someone who did not understand the problem.
Does anyone have any ideas ?
Thanks
Mike
