Maybe simple question.
How should I forward port internal 80 to port 8080 external to dynamic ip from my ISP.
I played with this a little, and it seems to work.
/ip firewall nat
add chain=dstnat action=redirect dst-port=80 to-ports=8080 dst-address-type=local protocol=tcp
You might want to check if this interferes with any other dstnat rules you have. If it does, add an in-interface=!ether1 to that rule.
