I am trying to connect via RDP from my PC to a server. They are in different networks (WAN) and the server is only visible via ipv6.
I cannot connect to this server from the network where my PC is located. I tried to use the same PC but a different network (from my smartphone) and it works fine.
So I assume something in my LAN is blocking RDP to ipv6.
So I tried to test and issue a ping -6 google.com for testing and it fails. "Ping request could not find host google.com". Ping with -4 works.
What should be the reason for this failure. How can I fix that?
Thanks.
ping google.com works by the way. IPv6 is also activated in my network adapter. I can RDP other external PCs using IPv4. – Igor Kondrasovas – 2019-06-17T12:16:27.460
I'm not overly familiar with Windows'
ping
(which I'm guessing this is), but could it be that-6
forces the name resolution itself to go via IPv6? Do you have an IPv6 DNS available and detected by Windows? – myxal – 2019-06-24T11:08:04.237I am not sure the DNS I am using supports IPv6, but I tried with google DNS servers on the network adapter properties, under ipv6 protocol,but it had no effect. Besides, I cannot connect (RDP) a remote computer giving its public ipv6 number, so I believe DNS would not play a role here. – Igor Kondrasovas – 2019-06-26T14:16:31.083
In that case, did you try pinging the computer's IPv6 address? Also, cannot connect is quite vague - what error is reported? – myxal – 2019-06-27T07:01:11.753
I think I have managed to isolate the problem I little bit more. I have two PCs connected to the same network. Both running Windows 10. One of them respond to thte ping command nicely, the other provides the error: Ping request could not find host google.com. Please check the name and try again. I have checked both network adapter have the same services enabled. What else could I check? – Igor Kondrasovas – 2019-06-27T14:51:11.650
Try comparing the lists under Adapter status -> Details. – myxal – 2019-06-28T08:31:41.613
