CCR1036-12g-4s and winbox

Hi, please help to provide me some information. I have a problem with Winbox connection with routerboard. I can’t connect to router form WAN with default Winbox service port (8291), if I changed port to 8292 it works. If i connect from local lan i can cannect with default port. OSrouter 6.2 version.
Now I am using just this rules:
0 ;;; Default
chain=forward action=accept protocol=icmp

1 ;;; Default TEO
chain=forward action=accept connection-state=established in-interface=ether1-Isorinis

2 ;;; Default TEO
chain=forward action=accept connection-state=related in-interface=ether1-Isorinis

and NAT
;;
chain=srcnat action=masquerade src-address=192.168.0.0/24 out-interface=ether1-Isorinis TEO

;;;
chain=dstnat action=dst-nat to-addresses=192.168.0.46 to-ports=3389 protocol=tcp dst-address=xx.xx.xx.xx in-interface=ether1-Isorinis dst-port=20090

Can Anyone help me? Thanks.

please double check your configuration. Especially your ‘/ip firewall filter’ section.
