Hello everyone i buy a new mikrotik router and i never used this type of router, after some hours reading docs i can open port 80 from an ubuntu server of my house… but i cant enter to the website if i’m conected to the router lan only from another connection i can get into the website hosted in my ubuntu server i try to enter from my mobile 4G and the connection is ok, but on the wifi or lan network mikrotik refuses my connection.
Hairpin nat.
Or run a DNS server on your RB750 and have the website URL resolved to the internal IP address.
