I thought astaro allows the returning/answer packets by default? Like if I create a PF rule like this:
10.1.1.100 -> HTTP(80) -> Any -> Allow
Then when that pc connects to 10.1.1.100:48975 -> 86.86.86.86:80 then returning packages also allowed without needing a PF rule: 86.86.86.86:80 -> 10.1.1.100:48975 -> allowed.
This is of course working as expected. But what I want to ask is if this is limited to http or any specific/known protocols?
Can anybody explain why the returning package is dropping every time?
08:58:35 Packet filter rule #8 TCP 10.1.1.2:38907→10.1.10.20:65000 [ACK FIN] len=40 ttl=62 tos=0x00 srcmac= dstmac=
08:58:35 Packet filter rule #39 TCP 10.1.10.20:65000→10.1.1.2:38907 [RST] len=40 ttl=62 tos=0x00 srcmac= dstmac=
I lack deep knowledge about TCP packages. So is it because 10.1.10.20 sending a RST package after ACK FIN?
Thanks.
