Ok I sort got it working and not sure how. I tried to force port 443 as it works at both home and office. At first it did not appear to work, then I restarted at home. Then it started working and worked until I paused sync at my work location. Then it never worked again until I restarted at home. Then noticed it was going through some kind of relay so for the heck of it, I removed the forced port number and went back to dynamic on the work side. Again it required me to restart at home but again it is working but via that relay.
Now I can give it 2 more ports but I would rather not leave my home router open if I don’t have to.
I am not too worried about the gui as everytime I restart at home, the port # changes and I have to find it so I won’t be using it often.
So would 2 ports do the trick if I forgot about the gui?
