FTP passive in vpn

Installing and Using OpenWrt
1

Hi, I'm trying to recreate an old setup with a FTP server in a OpenVPN network where router is OpenVPN client, but I cannot figure out what I'm missing. Clearest indication of the difference is when I'm trying to connect with FileZilla:

Working

227 Entering Passive Mode (10,8,3,133,122,220).
Binding data connection source IP to control connection source IP 10.8.0.2

Not working

227 Entering Passive Mode (192,168,1,102,174,111)
Destination IP of data connection does not match peer IP of control connection. Not binding source address of data connection.

10.8.0.2 is OpenVPN server. 10.8.3.133 is router in VPN of old working setup.192.168.1.102 is FTP server in LAN of new non-working setup.

Can somewone please point me in the right direction?

Tried port mode ?

Why not (Win)scp?

Is the server binding to the correct interfaces ?

Port mode isn't working either (LIST still fails).

I'm stuck with the server (vsFTPd) is on a locked down IoT device with no means of configuration.

I assume VPN is allowed to communicate with the LAN network ?
