Hi Today someone tried to connect with my BPFTP server, something which worked while I was using ESS5, but not with ESS6. The firewall was running in interactive mode. Everytime the client tried to connect, an allow/block popup appeared. I hit allow and enabled the checkbox to create a rule but the popups kept coming back and the client was still unable to connect. Then I noticed the external port was different on every popup. So I created a firewall rule for BPFTP server that allowed all traffic on all ports from that particular IP-address. .... No luck, still lot's of popups and user can't connect. Then I created a rule that allowed all traffic on all ports from all sources to the FTP server. Still no go. Then I switched from interactive to automatic mode with exceptions and it works. Now I would like to know what kind of differences there are between those two modes that could cause this. The only thing I can think of is that interactive mode ignores user defined rules.... Does anyone have any thoughts on this?
