I went back to a site where I installed Untangle over a year ago, any everything is working fine.. EXCEPT...
I setup FileZilla Server on a machine today. It works fine internal. However, when I try from outside, I can't get through. I don't get a welcome message or anything, which suggests its getting stopped at the firewall..
The setup. ISP is internet over fibre, with a direct connection coming into Untangle, set with a static IP. I have set my port forward as noted in the screenshot below:
I even tried turning off FTP processing. I have disabled the virus blocker for testing as well.
Looking for suggestions.
