Hi all,
I'm using the load balancer functionality from pfSense to split our
traffic to 2 different WAN lines. This works very good so far.
Since 1.0-release I have troubles with ftp traffic. Connecting to a
ftp server and executing commands over the control port 21 works
without any problems. But as soon as I execute a command that needs a
ftp data channel, I get troubles. Often the ftp connection simple
hangs, no directory listing comes back.
The problem is that many ftp servers do not accept data channels from
a source ip that is different to the control channel.
No problem, I thought, I simply configure a rule that makes sure,
that all ftp traffic is routed over the same wan line (no load
balancing). But since the source- and destination TCP port of such a
data channel is choosen by the ftp server and is "something beyond
port 1023", I do not have any idea how I could do this.
Sorry but load balancing and FTP will not be possible with version
1.0. And most likely not even with future versions. Just too many
issues with the FTP Proxy userland helper.
