My OpenVPN client cannot connect to server

yzleandro:

GLDDNS doesn’t seem to resolve to an IPv6 address, even if I enabled IPv6 on the GL-AR750S router.

IPV6 is just added now. But may need firmware update.

yzleandro:

I am not sure if the OpenVPN server app supports IPv6 on GL-AR750S router.

The same. Need to update firmware.

hey @alzhao ,

I just updated my firmware to 3.215. Are you sure the OpenVPN server on the router supports IPv6? I can see the config file .ovpn only lists my public IPv4 address. How should I properly set it up via IPv6?

And my DDNS ax11233.glddns.com still does not resolve to an IPv6, but only an IPv4 address.

alzhao · 2022-10-13T10:24:00.717Z

No. 3.215 still does not support ipv6 for vpn server.

yzleandro · 2022-10-13T11:37:07.155Z

@alzhao Hmm but that’s the latest version I got when I go to the Upgrade tab on the admin portal. What version supports ipv6 server and how do I upgrade to it?

I also suspected that your ISP was not assigning you a fixed IPv4, but that is not very common and seemed unlikely.

There is a 3.215 beta4 firmware available, but I do not know if it supports IPv6 for OpenVPN. It may be that GL.iNet has to develop a new firmware release.

yzleandro · 2022-10-13T17:52:13.440Z

Yes my ISP does not assign me a fixed IPv4. It is stated on their website. They do, however, assign me fixed IPv6. Unfortunately I only have a public IPv4 that is shared with other home routers (other customers in the building probably), and my home router is not directly connected to the Internet, but only connect to a layer of subnetwork with the internal IP (started with 10.x.x.x). So now I have no choice but to use IPv6 protocal for OpenVPN server.

@alzhao What version of firmware supports ipv6 OpenVPN server? and How do I upgrade to it?

alzhao · 2022-10-14T03:03:32.385Z

The latest firmware should support ipv6 in wireguard and openvpn.

It may have bugs though.

alzhao:

@alzhao You just told me “ No. 3.215 still does not support ipv6 for vpn server”. So what is the version number that starts to support it? Could you be specific?

alzhao · 2022-10-14T03:42:59.510Z

Sorry I messed up.

It has limited support for IPV6 when using vpn client.

It does not have support for IPV6 when using as vpn server.

yzleandro · 2022-10-14T03:55:28.627Z

Gotcha. That’s a bummer though. Do you have plan to support it in the near future?

alzhao · 2022-10-14T03:57:21.214Z

yzleandro:

Yes. Will add support for sure.

Hi wcs2228,
I´m a newbie and sorry for such a simple question. Regarding your comment: Have you enabled Dynamic DNS (DDNS) on the server router and edited the client config file to replace IP address in the “remote” line with the DDNS domain name (xxx.glddns.com
I have edited the client.ovpn file and now can you pls tell me how can I load the new file in the openvpn server.
Many thanks in advance for your help

admon · 2024-05-27T10:05:10.615Z

There is no need to upload the new config to the server. It's a client config.

fmas2 · 2024-05-27T10:17:05.655Z

Hi admon, sorry but I´m talking about editing the client.ovpn file created by the server and not the openvpn.ovpn file created on the client server when loading a vpn provider configuration

admon · 2024-05-27T10:23:37.519Z

So what is your issue right now? And what do you want to do?

fmas2 · 2024-05-27T10:35:37.813Z

The client.ovpn file has this remote 83.40.53.77 1194
and I want to change it with the the remote glddns info and then load it in the openvpn server.
Is that possible?

admon · 2024-05-27T10:52:07.467Z

I don't understand why you want to upload it to some server? It's the client config.

If you want to change the remote address, you need to adjust it on the server - because the server generates the new config every time you ask them for a download.

While downloading, it will even ask you about whether to use DDNS or not.

Ah OK! I was asking because user wcs2228 was saying to do this. However on gl.inet openvpn server when you start it doesn´t ask to use ddns or not. Thanks once again

fmas2 · 2024-05-27T12:00:29.907Z

Hi again admon, I finally understood that the client.ovpn file created by the openvpn server, once edited with the ddns info, is the file to be loaded on the openvpn client. Sorry for such a simple question

admon · 2024-05-27T12:08:27.873Z

No problem, sometimes even a simple task can be difficult - all fine, that's why we are here
