Issues with ftp-proxy plugin on Multi-WAN

[opns_neuling]

Hello @community,

Issues with os-ftp-proxy plugin

At Opnsense HA with 2 WAN Interfaces.
Haproxy Working, no problems.

Connect to FTP
on WAN1: connect, login and file transfer posible
on WAN2: connect and login works, but   file transfer not posible
Any Hints ?
Thanks a lot

PS: configured as in the guide https://forum.opnsense.org/index.php?topic=3868.0

Hi
PORT or PASV?
If its PASV, how your backend server knows which external IP to use in pasv response?
(i think that ftp-proxy should rewrite addresses in commands. but who knows..)
even more likely - its a routes issue (may be some reply-to / route-to directives are not set by ftp-proxy in anchor rules)
connection logs + fw logs may clarify the picture
