Ftp server behind firewall and vpn tunnel

I have a FTP server called Ftptran sitting behind a PIX "interface general"
a. My network diagram   fig 1
Traffic from the ftpserver should pass the pix to the VPN then the destination. I'm having problem with the tunnel , the problem is with my local host " Ftptran"
                          Trouble shoot  I did so far , see   fig 2
Either a ping or traceroute go past the server.
b. attached is the traceroute from the Ftptran.  
  I issed the command Pix: debug icmp trace
as you can see, no icmp is passing out of the ftptran or through the firewall

My ?. how can I configure the tracerout th pass the PIx interface and I need help
The tunnel will not create because the remote site  "host" is not able to connect to my host "ftptan"

attached is my pix file

It seems you skipped the diagram and posted the config twice.  And within that it seems some info is missing :)

I am sorry, this is the Network diagram

Ok, these 2 are at least wrong:

no static (inside,general) 10.40.15.20 10.40.15.20 netmask 255.255.255.255 0 0
no static (inside,general) 10.40.15.0 10.40.15.0 netmask 255.255.255.0 0 0

And you seem to lack a translation for the network you are trying to reach:

static (inside,general) 170.138.220.0 170.138.220.0 netmask 255.255.255.0

I should remove this 2
no static (inside,general) 10.40.15.20 10.40.15.20 netmask 255.255.255.255 0 0
no static (inside,general) 10.40.15.0 10.40.15.0 netmask 255.255.255.0 0 0
don't i need a translation from inside interface to general interface ?.

I added this
static (inside,general) 170.138.220.0 170.138.220.0 netmask 255.255.255.0

Thanks for the clerification.
I have removed both static  command.
I will have the remote site to fire-up the VPN tunnel with they gets to the office this afternoon.

2). When I issued the command traceroute 178.132.220.16 { is the gateway of the remove site) from my Ftptran ( 10.40.15.20 ---> 68.68.68.238)  and then issue on my Pix: debug icmp trace,. The trace command does nothing and also no packet on the Pix log.

The reason I do the trace command is to see if the packets go through the VPN concentrator  or through the Peremiter Router into the Internet.
The question is, how can I have the trace command  to work.
Thanks
It seems the FTP server is a unix, so you need the -I or whatever makes it into ICMP at least.
And if you are tracing inbound, you should also add this cmd to PIX:

fixup proto icmp error
