How to configure TMG's FTP over HTTP

[robertscoberg]

Hello all, I'm currently migrating a TMG to Palo and have come across a rule that uses the protocol "FTP over HTTP".  I'm not a TMG expert so the above is about all I know of the rule - that and what Mr Google tells me.

Any idea how to configure this rule in to the Palo (the customer does not want to simply open port 80 - plus with a command and ftp-data port it is likely not that simple)?

Many thanks

Robert

Hey Robert,

Welcome to the community!

So, ftp-over-HTTP is accessing the server in the browser by ftp:// instead of http://. An example would be - ftp://speedtest.tele2.net/ 

This shows a page like the below:

Palo Alto is smart enough to recognize the underlying application which is 'ftp'. The logs from my attempt:

Now, most FTP servers do (and imo should) function as 'Passive' server. Meaning, the client would make the data connection after the control connection, which is what's shown in the screenshot above. 

If the FTP server is in Active state, then you'd have to allow inbound connection from the server to the client. FYI - I am assuming that the client is behind the firewall and the FTP server is outside somewhere in the www.

Anurag, thanks for taking the time to repsonse. Reading your response I'm still not sure how this ends up being configured on the Palo.

Do I need to create an applcation override for this ( https://live.paloaltonetworks.com/t5/Configuration-Articles/How-to-Create-an-Application-Override-fo... ) or can I somehow just do it via basic firewall rule parameters?

Thanks!

Hi Robert

This can be done with a basic firewallrule. Simply add source zone/address and destination zone/address and then ftp as application with application-default as service and your done. (FTP over HTTP on a TMG is, if my short google search was correct, nothing else than a normal FTP connection opened in Internet Explorer or another browser)
