I need to connect from remote with VNC to a device connected to my MR600.

I have a no-IP account and I have configured it in the dynamic DNS router settings.

Then I have added a virtual server using my device IP FIXED addres (an IP outside the DHCP range) and setting port 5900 (inside and outside), the port used by UltraVNC.

I have verified that the router IP address is the same I find in my no-IP account and it is not in the private IP address range.

If I use the command "nslookup mynoipdomain" I get the correct IP.

But when I try to connect from my pc to the device using UltraVnc, it doesn't work.

If I connect my pc to the MR600 with a cable and I Use UltraVNC with the fixed IP assignet to my device, it works fine.

What is wrong?

Someone can help me?

Thanks.
