Hey there,
I hope this thread hasn't been here before but I tried multiple browsers, the search function is broken for me.
I wanted to use FileZilla FTP in order to save snapshots from a webcam in an external network. I have set up FileZilla on a server (lets say 192.168.100.10) with custom ftp ports (59000 for FTP and 59001 for passive mode), configured the server's firewall to allow traffic on port 59000 and 59001 and set up the camera. Everything worked in my internal network and the camera saved the jpg files into my FTP folder.
I then created a DNAT rule in my UTM, as I have done plenty of times with different services before, and let it create a firewall rule for me. Coming from any, ports begin source 1:65535 to destination port 59000:59001 and my external destination adress (lets say 100.10.10.100) and changed the target to 192.168.100.10
I then added the webcam to an external network, changed the ftp adress from internal 192.168.100.10 to external 100.10.10.100. It can log into the FTP server, but it can not edit files. It starts a session, goes into the directory and has access, creates a 0kb jpg file and then times out. This does not happen from an internal network which leads me to believe it has to do with my UTM and im seriously lost. I found another person making a guide on how to set up Filezilla behind a UTM and creating the DNAT rule with an auto firewall rule is the only thing he does as well. I also tried disabling the server's firewall completely, giving all users full file and folder access and changing the ports in my firewall, filezilla and UTM back to 20/21. Doesnt change.
Can anyone give me ideas on what to look into? FTP Proxy is disabled btw.
