Hi, I just started to use 5g home Internet with T-Mobile. Their gateway doesn't have a network drive connection, I connected my Linksys router to the T-Mobile 5g gateway with Ethernet cable and everything works except my network drive ( connected to Linksys router). In the lan side I can connect to the network drive but I can't find a way to make a external FTP connection to it on the Internet. Anyone has a working way for this? Thanks in advance.
