Client FTP Proxy on ipsec interface

[vMario]

Hello

I have installed Client FTP proxy on Pfsense firewwall (2.4.5) When I have the client FTP located behind the "local" interface everything works OK. Below redirection rule:

rdr pass on em9 inet proto tcp from any to any port = ftp -> 127.0.0.1 port 8021

In case when I have a FTP client located behind the VPN and even redirect rules configured, the traffic is not passing via IPSEC interface.

rdr pass on ipsec1000 inet proto tcp from any to any port = ftp -> 127.0.0.1 port 8021
rdr pass on ipsec2000 inet proto tcp from any to any port = ftp -> 127.0.0.1 port 8021

The VPN is route based using VTI interfaces. Is there any limitation of using VTI's along with FTP proxy?

Regards
