Dropped invalid packets?

Fri Oct 09, 2015 8:28 pm

So there's a default firewall rule to drop invalid fwd packets. I enabled logging on that rule and I see lots of stuff getting dropped. What's the deal here? Something in my setup? Below are the log entries, I can paste exports if needed.
3:22:33 firewall,info [DROP INVALID FWD]  forward: in:vlan101 out:WAN, src-mac a4:5e:60:c6:22:1d, proto TCP (ACK,FIN), 10.1.1.14:54067->XXX.XXX.XXX.XXX:443, len 40
13:22:34 firewall,info [DROP INVALID FWD]  forward: in:vlan101 out:WAN, src-mac a4:5e:60:c6:22:1d, proto TCP (ACK,RST), 10.1.1.15:54325->XXX.XXX.XXX.XXX:80, len 40
13:22:35 firewall,info [DROP INVALID FWD]  forward: in:vlan101 out:WAN, src-mac a4:5e:60:c6:22:1d, proto TCP (ACK,FIN), 10.1.1.14:54067->XXX.XXX.XXX.XXX:443, len 40
