I have a MikroTik Antenna which has a '3 sim' card in it. I can download and upload OK, but for my work I need to be able to connect to websites using FTP over SSL but I am finding port 21 is blocked on my '3 Network' All my firewall settings are disabled, so it is not the firewall.
My installer says it is the '3 sim' and '3' say it is the Microtik dish.
Has anyone else had this problem or even better know a solution or where the fault is and how it can be fixed?
This is a link to a photo of the dish - sorry it is on top of the house so only have a photo cant see model number
Thank you
