I am trying to connect to a shared hosting FTP server via port 21 but its blocked by my ISP. I'm using an internet dongle. I'm travelling and must use the dongle since there is no other wired internet or Wifi in this remote region. I contacted the host and they refuse to change the port for a single site. Port 990 is unavailable as my host offers FTPS on port 21 itself.
So how do I connect to an FTP server on port 21 when the port is blocked by my ISP? FTP Proxies? I have a locally setup Windows Server that I could install custom apps on.
