I block most everything with my firewall, what I don't get is why would I constantly receive hits to connect on random ports from port 443.
[iptables] reject_ipv6: IN=eno1 OUT= MAC=...
DST=<one of my IPv6 IPs>
LEN=80 TC=32 HOPLIMIT=120 FLOWLBL=753719 PROTO=TCP
SPT=443 DPT=33820 WINDOW=65535 RES=0x00 ACK SYN URGP=0
As far as I know, I do not own IP address 2607:f8b0:4005:0805:0000:0000:0000:200e so it's not coming from one of my computers.
Is that an attempt to hijack an existing connection that would (by chance) by using port 33820 (a.k.a. the destination port) on my server?
