I want to ask for help.
I have a Mikrotik LHG LTE device.
Its local IP address is 192.168.88.1
Behind it is a Tp-link router with an IP address of 192.168.0.1
(This device receives a 192.168.88.200 WAN IP address from Mikrotik.)
Behind this TP-link router is a set top box with a local IP address of 192.168.0.18
I would like to open FTP port 21 of this set top box to the internet on external port 21212.
How do I configure NAT and HAIRPIN NAT?
I don't see the router's admin interface from the internet either, even though DDNS is turned on in the CLOUD menu. The LHG device responds to Ping.
Thanks.
