Remote Desktop connection drops constantly

vicente.canhoto — Thu, 10 Jan 2019 22:19:41 GMT

Hi,

Since moving to a new house and receiving a new modem, I have not been able to Remote Desktop via VPN to my work office. I also connect to the VPN, and the Remote Desktop also connects, but after a few seconds the Remote Desktop is closed.

Does anybody have any ideas of what I can do? Or do I need a new modem?

Thanks in advance,
Vicente Canhoto

Possible solution:

Do you see a IPv6 adres under IPv6 connectivity http://ipv6-test.com ?

If there is, aks the chat to put your modem in IPv4 modus.

Thank you for your quick reply!

I don't see any IPv6 address in that test, but a couple of weeks ago I tried the same test (according to some other questions that I read in this forum) and I think I remember seeing an IPv6 address there. I also tried making some changes in the modem settings, and I might have disabled something related to that. When I check those modem settings, I see an IPv6 address. Should I still ask to put the modem in IPv4 modus?

Vincente,

First of all: when http://ipv6-test.com shows no IPv6 address
it just tells you that the system you use for the test did not get a global IPv6 address.

Maybe it should have an IPv6 address, but it was not assigned by the IPv6 Router Firmware for some (strange) reason. As such this is not a real problem. We can look into this, later on.
You write that you see that the Router has an IPv6 address. I presume that you have a ConnectBox. Am I right?

Let's determine what kind of IPv6 Firmware the ConnectBox runs.
I included 2 images, as examples.
Image 1: DS-Lite firmware; CB has only an IPv6 address
Image 2: Dual Stack firmware: CB has both an IPv4 and IPv6 address
What do you see?

Since you can setup a VPN connection to your work office, I don't think that
IPv4 Firmware will solve your problem.
As I understand the Rdp Connection to a host in the Office network over that VPN connection fails in a few seconds, but the VPN Connection does not drop.
Can you confirm this?
Do you use other facilities of your office during a VPN session, like Network disk shares?

Regards Han

Hi Han,

Thank you for your help. Yes, I do have a ConnectBox, with DS-firmware, as you can see in the image attached.

Besides the Remote Desktop, I used to be able to open sites with the VPN connection that are only accessible in the office network, but now I tried it and also didn't work.

I can confirm that the VPN connection does not drop. The first time I connect to the Remote Desktop I can actually see my work desktop for a few seconds, until the Remote Desktop connection drops.

Thanks!
Vicente

Ik think it is DS-Lite.

IPv4 is shared with 20 others, so there is no IPv4 only for you and the RD stops.

Ask the chat to put your modem in IPv4 only:

Hi Vicente,
Thanks for your info. So the VPN Connection as such is not your problem.

Mostly DS-Lite on the ConnectBox gives problems with starting a VPN Connection at all.
It's beyond my imagination why the VPN Connection itself succeeds & holds, but
the use of a service through that connection fails.

I don't think that further investigation makes sense in your case.
I actually don't even know where to start to tackle the problem in an effective way.

So: step over to IPv4 Firmware, like Bert suggests.
This may solve your problem without understanding what's exactly going wrong now. Looked around a bit, but didn't find sources yet that confirm that a good DS-Lite implementation should technically not be able to perform the tasks you need.
So be it.

Please, let us know the result.

Regards, Han

After asking Customer Support to switch to IPv4, it worked! Thank you guys for helping.
