I'm running ASG 8.202 on a dedicated machine with 5 NICs.
Two of them (WAN1, WAN2) are connected to the internet using different providers. Provider at WAN1 offered a limited data transfer volume per month, let's say 10 GB. But, he's routing a /29 subnet with offical ip addresses to me [:)] WAN1 has a static ip address not belonging to this /29 net.
The other one at WAN2 offers a flat rate with dynamic ip address.
Following this article I implemented a multipath rule to force outgoing http/s traffic to WAN2. Furthermore I'm running webfilter as http/s proxy. This works fine for me without any problems.
But, now I decided to send outgoing ftp-connections through WAN2 also.
Doing so I defined a new multipath-rule:
Any => FTP (Control, TCP Port 21) => Any => WAN2
After activating this rule, active FTP-Traffic works fine, using the FTP-proxy, anyway if in transparent or non-transparent mode.
But, this is not what I really want. Actually I'd like to use passive mode only. Trying to establish a passive mode connection with the settings described above I got the following ftp (client) log:

Well, actually the new multipath rule should work for ftp controll session (TCP port 21) only. So I added a further multipath rule for outgoing ftp data sessions (TPC port 20), but this didn't help to fix the problem. The result using passive mode ftp connections is the same as described above - none!
Any idea what's going wrong and what to do for fixing it? Can't FTP proxy be used with multipath rules and passive ftp?
Running FTP-Proxy on WAN1 anything works fine, i.e. in both modes (transparent / non-transparent) and in active and passive transfer mode.
