I have LHG LTE kit and I am connected to Internet over LTE network. I also use NoIP service to be able to access it using symbolic name (since actual IP address changes every 24h).
I would like to re-direct TCP traffic on port 21 to local FTP server on local address 192.168.88.100, so I would be able to access it from anywhere.
After I googled how to do it (also on Mikrotik Wiki page), I have found some guides which resulted in this configuration (output of print command)
0 ;;; defconf: masquerade
chain=srcnat action=masquerade out-interface-list=WAN log=no log-prefix="" ipsec-policy=out,none
1 chain=dstnat action=dst-nat to-addresses=192.168.88.100 protocol=tcp dst-port=21
However, I cannot access server externally. I cannot figure out what am I doing wrong and any advice will be helpful. Thanks.
