      Please, someone explain is it normally or not. I have read about this , but still in doubt, This is normally or something wrong with a rule or traffic passing. This is log entry regarding rule to pass VPN traffic over poxy port VPN provider. Vpn use UDP protocol, btw!

        I'm not sure what you're asking here.

        Given that floating, quick, outbound rule, traffic to the remote proxy that leaves the VPN will open a state like that, yes.

        What exactly is that rule supposed to be doing?

          I have a rule to block RFC 1918 from WAN and without this rule above block RFC do not have internet access.

          and firewall log show protocol TPC-S from any 10.0.0.0/8 to 10.8.0.1. The question , is it suppose to be normally in this case?

            Yes, that's what I'd expect to see given that rule.

                        @johnpoz said in Firewall log TCP -S:

                        curious let see if you get any hits on those ;)

                        Probably depends on what types of clients are behind the firewall. I'd certainly expect some hits on some of those.
