I am in front of a new for me problem on my new Routerboard 411.
I have set it with NAT / masquared and I need to give access from out site to my FTP server that exist in the inside.
What filter rule I must give give them access to my FTP server?
you must make a new NAT rule with the action dst-nat. you will have to specify the port (the FTP port) and the to-address (where the connection will be sent)
dst-address = address of router’s public inteface
dst-port - connections going to this port will be affected by the rule
to-addresses - where you will redirect to
to-port - port on the above address where you will redirect to
