Blocking TCP:RA, TCP:FPA,TCP:A
I have the attached rules in my LAN and OpenVPN IFs. However, there are still rejected packets such as [Rst,Ack] and etc.. Do you have any idea of why?
Did you set any advanced features on the FW rules (LAN side?).
Seems to me like it should work.
No advanced firewall rules.
Can this be because of an invalid flag for the current state of TCP connection?
This is typical out of state being blocked..
Thanks for the answer.
