If you still have a Thompson Speedtouch 780 ADSL2+ router (for example you might be a Be Internet customer who signed up when they first opened, and received one of their first BeBox devices) here’s how to enable NAT Loopback on it…
NAT Loopback is where devices within your network can access each other by going through your router, as if they were connecting from outside your network.
On a Speedtouch 780 you do this by using Telnet to connect to the administrative console
yourcomputer:~ username$ telnet bebox Trying 192.168.1.254... Connected to bebox.piku.lan. Escape character is '^]'.
Once connected, log in with your admin username and password. If you forgot how to do this (maybe your BeBox was in the loft after being replaced by something much better) the username is Administrator.
Username : Administrator
Password : **********

Now type in the following commands
{Administrator}=>ip config natloopback=enabled
{Administrator}=>saveall
That’s it.
