      I'm talking about the local storage encrypt, non about the transfer ;) all the files are encrypted on the disk. Files are decrypted when downloaded and are transfered over https.

      I already use https from browser for upload and download and with webdav client the same using https.

        Anyway, my question was for the on-demand opening of passive doors...

        ....and can be possible to interact with pfsense using API from a web page? .. i want to create a PASS firewall rule when a client compile a protected form where will write her static ip , in order to allow access only to him.

          What indeed means, that it has nothing at all to do with running another protocol but is due to your local storage encryption thingy. So again, don't understand why you keep on mentioning that 150GB files would be harder/more CPU bound to transfer with any other possible (current, modern) transportation method. SFTP, HTTPS, etc. wouldn't need any more CPU cycles for 150G or 5G. If SFTP is slow I'd check with your target. Never seen that much difference on our customer hosting servers at all. More often it's a thing with the customers not updating their client software and using old/deprecated SSH/SSL ciphers/settings. I'd try updating clients etc. to ensure best protocols are used with hardware encryption in use etc. Had that discussions too many times like "But that tool worked for years!" - "Are there updates?" - updated tool multiple major versions "Wow it really is faster/is working now!" ;)

          But again, to stay in the OP: No passive port opening automagically as passive ports are configured on the server side and every server can declare them as they want. pfSense has an active FTP helper for outbound connections that could help with that but it relies on the other side offering active FTP - not everyone does that (or uses FTP at all these days).

          @openaspace said in FTP passive port on demand opening:

          Why? Passive FTP means you have inbound (if you host the server) or outbound connections with 21/tcp as well as xxxxx-yyyyy/tcp. So if it's your own FTP server where you upload your huge file stuff, why not allow your passive port range to your specific IP? Don't get the problem with opening passive ports here?

            As I already answered in my first post, there is no passive helper or way for pfsense to auto open the passive ports. If you want to provide passive ftp as an option to your ftp server then you need to set your ftp server to use a specific range of ports for its passive connections. And then forward that range.

            You can for sure lock down the source IPs on this forward/firewall rule.

              Yes, I will see if is possible to interact with pfsense using api to do this

                @JeGr it's well known that an sftp process use more cpu

                  Your more than welcome to tinker all you want - but would be akin to coming up with a faster way to read floppy disks.. Nobody uses them ;)

                  Sure there is a huge user base for something like this - the 3 people still using ftp will love you I am sure ;)

                          Just to add 0.02$: Again depending on the cipher and setup used. And it's documented, that it strongly depends on you configuration of SSH. Also speed comparisons are available that show that modern versions of SSH that are patched for the old problems of high latency or window sizes aren't far behind in transfer speed. So modern ciphers like AES-CTR deal with single/multi-core problems and you can hit a 1gpbs bandwith limit if you do a little bit of homework and don't use ice-age-old versions of your toolchain ;)

                                Besides your question solved - what about actually reading what I wrote? You show some graphs with no intel whatsoever. As I said, if you set it up right, it CAN work the same without pulling your leg. How should I know what old software you're running? I can show you graphs all day long - without details they tell you nothing other that you seem to be having a bad SSH setup. shrug But hey, if one wants to see problems as nails to use their hammer, that's nice. Have fun hammering :)

                                  What cipher is being used for these connections... There can be some huge difference in speed and cpu cost.. And if the box supports say aes-ni, etc..

                                  Simple test here locally.. using just chacha20 vs aes256-ctr and go from like 75MBps, to full gig at 111 and pretty good drop in cpu usage as well. Now I am a fan of chacha.. But if what your looking for is fastest speed with lowest resources used... Then yes you have to take a few minutes to config your stuff and not just turn it on.. This goes for everything in the IT world.
