I've got a strange problem that manifested with my firewall logging denied connections back to my clients. To investigate it further I tcpdumped and wiresharked the capture:-
So the RST sent by chrome doesn't get received by the server somehow and it continues to send the resend the [FIN ACK] until it's eventually blocked by the firewall.
To demonstrate here is the same behaviour with ipv4:-
and here is a iptables firewall log:-
Firefox exhibits no such problems, presumably it doesn't RST the connection.
So I'm confused about what the problem is, the ipv4 connection is with nat, other than that same kit, edgerouter lite, linux iptables.
