[lwip-users] Tunnel solution for HTTP server expose to Internet

[Giuseppe Modugno]

My embedded device, running lwip httpd server, is under a router with a 
dynamic public IP address and a local private network 192.168.1.x. I 
know how to configure DDNS and NAT on the router to reach the server 
from outside, but these are tedious and tricky steps for most users.

So I'm searching more "plug&play" solutions that would allow the end 
user to connect to my embedded device. I found yaler, pakekite and some 
others. They should work, but all solutions need the installation of a 
piece of software in the embedded HTTP server, in my case lwip-based.

Do you have any experiences on implementing this protocols on lwip to 
expose httpd to Internet? Could you suggest any other better solutions?
