Access Mikrotik Webfig/Winbox remotely thru DDNS address

I have problem to access my mikrotik webfig or winbox thru DDNS address on separate network. I already added DDNS script from changeip.net, allow port 80,8291 to outside. But i still got no response error from winbox and page loading error on webfig. Any step I missing?

This is my ip firewall filter and nat export:

/ip firewall filter
add action=accept chain=input disabled=no dst-port=80,8291 protocol=tcp
add action=passthrough chain=unused-hs-chain comment="place hotspot rules here" \
    disabled=yes
add action=accept chain=input comment="default configuration" disabled=no \
    protocol=icmp
add action=accept chain=input comment="default configuration" connection-state=\
    established disabled=no
add action=accept chain=input comment="default configuration" connection-state=\
    related disabled=no
add action=drop chain=input comment="default configuration" disabled=no \
    in-interface=ether1-gateway




/ip firewall nat
add action=dst-nat chain=dstnat disabled=yes dst-address=113.210.134.73 \
    dst-port=80 protocol=tcp to-addresses=192.168.88.1 to-ports=80
add action=dst-nat chain=dstnat disabled=yes dst-address=113.210.134.73 \
    dst-port=8291 protocol=tcp to-addresses=192.168.88.1 to-ports=8291
add action=passthrough chain=unused-hs-chain comment="place hotspot rules here
    disabled=yes to-addresses=0.0.0.0
add action=masquerade chain=srcnat comment="default configuration" disabled=no
    out-interface=ether1-gateway to-addresses=0.0.0.0
add action=masquerade chain=srcnat comment="masquerade hotspot network" \
    disabled=no src-address=192.168.88.0/24 to-addresses=0.0.0.0

FYI, I am using RB751G-2HnD and internet connection from 3G modem. Any response would be appreciate. :slight_smile:
