[En-Nut-Discussion] FTP access behind router

[Peter Sodermanns]

Hi group,

I have an Ethernut 2.1b device working as HTTP- and FTP-Server. In 
intranet it's no problem to access both (on an HTML-page I put a link 
containing "ftp://192.168.1.1/").

But behind a NAT router this cannot work. I can connect via HTTP since 
the router has a fix IP-address but the device knows nothing about that.

Even worse, I tried to connect to that given IP-address with filezilla 
and reached a server which was not my device. So even if I would store 
that external IP-Address in my device, I wouldn't reach it.

Does anyone know a solution?


Thanks in advance
