FTP not working in my network with Sophos UTM 9

William Ribeirio

 Hi all, 

 

 I'm new on Sophos UTM and one internal department needs FTP access to a URL on the internet. It works fine if the laptop is out of the network and but it doesn't when it's behind the UTM.

 I read some posts of people having the same problem. Here is what I've done so far.

 - I have a rule allowing everything from the laptop I'm testing it from

 - I enabled FTP proxy and tried in Transparent, Non-transparent and Both modes, and I allowed the internal network

 - The Web Filtering is set in Transparent Mode

 

 Would you guys know what I'm missing here.

 

 Thanks.

 

 William

    First, make sure that FTP is enabled under Network Protection > Firewall > Advanced > Connection Tracking Helpers. And are you sure this is FTP, not SFTP or FTPS?

     

    In our environment we have very few users that need access to FTP, so I haven not used the FTP proxy. Web filtering is in standard mode and firewall rules are used to allow FTP from specific host/networks to specific endpoints. I found it more trouble to configure various ftp clients to use the ftp proxy than it was to create a few rules for the limited use.
