I have successfully set up the system and generally it works well.

I just have issued with two applications on Macs that have issues & I cant work out why.  Both work fine if I swap to an iphone hotspot.

Mac Mail - wont connect to download emails.

An FTP programme I use to download large amounts of data from from my office server (Cyberduck) that either wont connect or gets half way through a big downlaod then stops.)

I have tried disabling the router antivirus etc.

Any thoughts what might be blocking this data?

Thanks
