I can't ping between lan (192.168.1.199) and wlan (192.168.1.177).
Both machines can ping OpenWRT (192.168.1.1)
Can you help please?
What is FORWARD option for the zone, containing interfaces?
no, more information is needed. how does your config look like?
It is wlan, wireless, not wan.
Yes, but it should work, because 'Forward' of lan is 'accept'. Try to ping devices from command line of router itself.
