Thanks for the tutorial, but I have done it on different approach, so I don’t need to do hairpin nat. My config is like this:
/ip firewall nat add action=dst-nat chain=dstnat comment="Port forward" dst-port=5001 protocol=tcp dst-address-type=local dst-address-list=!router to-addresses=192.168.0.8 to-ports=5001
Whereas the address list for “router” is your router gateway addresses on /ip address. With this setup you don’t need to have a hairpin nat rule.
