Speedtouch and NAT Loopback

My Speedtouch 780WL has an option called NAT Loopback that allows you to access the external IP address from inside your home network. This is useful because if you run a server inside your network you can use the same IP address (and so hostname) to address the server both at home and when you are outside. To enabled NAT Loopback login to the command line (through telnet) and enter: ip config natloopback=enabled saveall Then it should all work (maybe after a reboot). The only gotcha is that it doesn't seem to loopback ICMP packets so you won't be able to ping the external IP.

Hi!!. I have done the same but I do not work, because I have a static NAT. Any idea to solve my problem? Thank you very much.
