First hello everyone and a big thank you for rejetto and his HFS!
I have managed to install and to create a little web server with his tool.
So I can browse different files within my network.
That's ok.
I've got a permanent Ip with No-ip and now I try to access to my files outside my network but...
...I have some problems:
I have 2 routers.
One who is connected to DSL line and one who broadcast wifi.
A little bit like this:

Inside my network the Ip of my computer is 192.168.123.106
So i tried to forward this ip through my two routers.
No luck...I cannot acces to my files.
Did I miss something?
I don't know what I've done wrong so I give you all my network configuration:
First router (Thomson SpeedTouch 510) connected to the DSL signal:

Second router (Sitecom WL-114) broadcasting wifi:

I tried different thing like DMZ, changing ports and so but still unlucky...
I searched a little bit through the internet but I found nothing about my type of network.
If anyone has a clue...
Thanks in advance
(and sorry for my english...I'm coming from France so I try to do my best...)
