Route FTP Scanner between Two Site to Site VPN Tunnels

[NetFire]

Hello,

the scenario is the same as that I asked in the past but with the opposite direction.

My goal: reach the FTP server (192.168.177.2/32) which is "two FGT ahead" (from FTP Net Scanner 192.168.0.246/32)

My scenario:

[ul]

NET PRINTER / SCANNER (192.168.0.246/32) - Admin Access

FG_1 (192.168.0.0/24) - NO Admin Access

FG_2 (10.1.0.0/24) - Admin Access

FG_3 (192.168.177.0/24) - Admin Access

FTP SERVER (Win - 192.168.177.2) - Admin Access[/ul]

ALL VPNs WORKS

I have admin access only on FG_3 (192.168.177.0/24) and FG_2 (10.1.0.0/24).  No admin for FG_1 (192.168.0.0/24).

I tried to use the same procedure (but reversed) described in EMES's response but I think I must have an Admin Access on FG_1. 

In fact, if I insert 192.168.177.2 (IP address of the FTP server) in the scanner settings, obviously it is not reached because primarily, I must have to do a Static Route set on FG_1, [that would be the same thing done in the reverse path (Windows Server -> Printer)] but I can access on it.

Or 

use an empty  FG_2 IP (ie. 10.1.0.247) and  set it as destination FTP IP on scanner setting and do a route/translation on FG_2 from that IP (10.1.0.247) to 192.168.177.2 (ftp Server)... but I don't know how to do it.

Can someone save me?

Thank you so much for your help

You are going to need admin access in order to edit the Phase 2's to have the destination IPs if they don't already exist.

Either way, that's a convoluted way to approach things.

Is there ANY way you can gain access to the Gate1? Because a IPSec tunnel directly between Gate 1 and 3 would be the simplest route.
