We've recently had a customer install a cable internet connection to handle some large outbound FTP 'puts' to their customer's site. To handle this we've configured PBR, but are running into a problem when the client opens the secondary PASV port (which we can't always know before hand because it's configured by the FTP server).
Has anyone dealt with this before? As a work around we've configured a destination route but this of course requires the customer to inform us everytime there's a new FTP site to be reached. Additional PBR configuration for SCP/SSH works properly.
