Re: Remote access to ECOS web server from internet




Hi,

Thanks for your suggestions.
I checked the packages. Request came to my device and my device sends ARP to modem but after that time,
no packets go out of my device. When I reach home page from local, everything is ok (packets are appropriate)
but, my web browser does not detect the type of the home page (it must be HTML document).

I didn't understand which causes a problem and difference while reaching from local and reaching from outside.

Regards,
Alperen
