hello

beginner here, when firewall/filer drop to all the dst nat added in filter wont redirect can someone check my configuration if it correct?

(nat)
chain=dstnat action=dst-nat to-addresses=192.168.80.3 to-ports=8443
protocol=tcp in-interface=ether1 WAN dst-port=8443 log=yes log-prefix=“”

(firewall/filter)
chain=forward action=accept connection-state=established,related connection-nat-state=dstnat
in-interface=ether1 WAN log=no log-prefix=“”

chain=forward action=drop out-interface=ether1 WAN log=no log-prefix=“”

thank you

You are missing the “new” connection-state.
When a packet first comes to the router its a “new” connection
Subsequent packets for that connection are “established”
Or “related” if firewall helper is used

Last rule drops everything coming to WAN trough router, it’s like one way street. BTW, what’s the purpose of this rule?

Cannot comment accurately until one sees the config as a whole as parts are interelated.
