[6lbr-dev] Web Administration SSL/TLS Support?

Hi Ron,

Actually we don't plan to add SSL/TLS support on the webserver of 6LBR. 
The webserver itself is Contiki based and should work on small devices 
(like CC2538) as well as Linux box, and maintaining two different code 
is not feasible. So, your solution using NGINX as a https proxy is a 
good solution. We looked at apache which provides such a functionality 
out of the box using mod_proxy and mod_ssl (Using ProxyPass and 
You then only need to block the 6LBR webserver port to completely secure 
it. In the next develop I should add a configuration parameter to change 
the webserver port so you don't have conflict between Apache/nginx.

Kind regards,
