2.st router Omnitik
/ip firewall nat add chain=dstnat dst-address=192.168.4.2 protocol=tcp dst-port=8088 action=dstant to-address=10.10.10.20 to-port=8088
3.st router SXT
/ip firewall nat add chain=dstnat dst-address=10.10.10.20 protocol=tcp dst-port=8088 action=dstnat to-address-192.168.103.99 to-port=80
