I'm seeing entries like this in the state table. I originally discovered this on my router which was running a -current May 24th snap. I've upgraded it via source yesterday and the output remains.
tcp 192.168.0.1/128:22 <- 192.168.0.2/128:5503 ESTABLISHED:ESTABLISHED tcp 192.168.0.9/128:51059 <- 192.168.0.2/128:22 ESTABLISHED:ESTABLISHED tcp 192.168.0.9/128:51149 -> 192.168.0.2/128:22 ESTABLISHED:ESTABLISHED tcp 192.168.0.9/128:50940 -> 192.168.0.2/128:22 ESTABLISHED:ESTABLISHED I also upgraded some workstations which have pf running and they exhibit this problem too. All machines are dualstack ipv4/ipv6. This appears harmless as everything is working normally.
