in-interface=WAN protocol= tcp to-addresses=192.168.1.4
add action=dst-nat chain=dstnat dst-address=10.10.10.10 dst-port=137 \
in-interface=WAN protocol=tcp to-addresses=192.168.1.4
add action=dst- nat chain=dstnat dst-address=10.10.10.10 dst-port=445 \
in-interface=WAN protocol=tcp to-addresses=192.168.1.4
add action=dst-nat chain=dstnat dst-address=10.10.10.10 dst-port=138 \
in-interface=WAN protocol=tcp to-addresses=192.168.1.4
