FTP change source ip address

[DVO]

Dear everybody, 

we are currently facing an issue with FTP source ip address. I know that for some services (syslog, ...) it's possible to change source ip address, but i would like to do the same for FTP. Which seems t be really difficult (or maybe impossible?). 

In accord with attached image, we would like to open a FTP connection from fortigate 300D to send a backup to FTP server  behind a 1000D.

Ipsec VPN allows 192.168.0.0/24 and 192.168.10.0/24 networks.

Problem is, when FG300D try to connect to FTP, it use 192.168.1.99 ip address as source. I would like to be able to set 192.168.10.1 as FTP source ip address to be sure that it will be routed through IP-SEC vpn with a reachable ip address. 

All needed firewall policies are already implemented. No NAT is currently used on thesse 2 firewalls for this type of communications.

If you need more information, feel free to send a reply and i'll try to respond in short times.

Hope that someone have THE solution. 

Kind regards, 

Denis

Did you ever figure this out?

Did someone found a solution yet?

Have you tried creating an IP pool with the single address and using that in the FTP policy? This needs to be placed before the general policy for traffic between the FTP server and that remote site.
