I try for hours to get a connection from local machine (green 192.168.100.2) to a motioneyeos raspberry (orange DMZ) 192.168.200.3 but it just will not work out. I set 192.168.200.1 as DNS.
It works out fine on normal router but on ipfire orange as 192.168.200.3 there is no-go
E.g. why is this INPUT being dropped within DMZ Zone - i have no rule to deny that.
DROP_INPUT orange0 UDP 192.168.200.3 192.168.200.1 45502 53(DOMAIN)
