Hi,
I have a problem, dynu is working and updated ip, but when i do ping doesn't answer to me.

Why is there no answer when i ping to myhost.ddnsfree.com, but the service is active and all working fine??

Thanks
Regards

When you are doing a ping, you are pinging your router. You need to configure your router to allow ping traffic for ping to work.

Ping sends very small packets to an IP host who will answer by sending packets back.
The ICMP packets sent to the host are called echo_request and the packets sent back echo_response.

Routers are configured to reject ICMP packets by default.
