redirect by userid w/ ftp pool
I have a pool of ftp servers. I already have an irule directing inbound traffic to specific servers based on source IP. My customer has asked if I can direct incoming ftp based on userid. I said no...
Frank,
even in the case of FTP access from a browser, the connection to the FTP server has to be first established in order to be able to authenticate. The browser does not send anything until the server sends proper FTP server banner (220 ...).
Morevover, in v 4.x (any version) FTP virtual servers cannot utilize L7 iRules (i.e. rules parsing TCP content). or in other words, FTP virtual servers cannot be late-binding.Such configuration is (unfortunately) accepted both in CLI and GUI, but it does not (and cannot) work correctly.
