Note that other transfer limits, such as `MaxStoreFileSize` or `MaxRetrieveFileSize`, would also be useful for such use cases.

With support for proxying of SSH (see Issue #56), `mod_proxy` now has the basic building blocks needed for implementing this protocol translation feature. Now the question is: just which protocols...

@kdesjard @pedanticdan for your frontend FTP/FTPS use cases, would `mod_proxy` be used as a reverse proxy, or as a forward proxy, to the SFTP backend?

Hmm. Interesting situation. Currently, there isn't a way to configure a per-backend `ProxySourceAddress` -- but I can see how, in your case, it would be useful. Would it be possible...

I'm researching this, and in how exactly the Linux kernel will choose the source address to use for a given TCP connection, when the source address is not explicitly provided...

Recording this here for my future reference: this particular issue hinges on the value of `bind_addr` here: * https://github.com/Castaglia/proftpd-mod_proxy/blob/master/lib/proxy/conn.c#L752 Hopefully the provided logs/messages can help inform how and when to...

@jb-boin Thanks for the info! Based on the IP addresses, we can indeed see that the wrong interface is being used. The "Transport endpoint is not connected" is a somewhat...

Note that using the NetIO API for deflating might be complicated by the use of the same NetIO API for TLS connections; I'll have to see how hard it is...

One of the issues/tricks for this feature, I think, would be in automatically detecting whether the remote FTP server _can_ handle commands on the control connection while also handling a...
