Dear dynvpn community,

I’m running a dynvpn network with Linux Debian 8 and a few node running Debian 7 on a Gigabyte Server Hardware.

It seems that the clients with Debian 7 are working fine, but the majority is on Debian 8 and is not connecting.

I have tried many commands and settings on my testsystem (same HW and SW like the clients) but no help.

Please do you have any idea what’s wrong?

Thank you for your help.

Here are some settings and Output:

thats how the interfaces look like:

Hi Ferit,

If you use an all linux network I suggest that you have a look at the new beta platform that we just released.

Dashboard to register: https://my.dynvpn.com and https://doc.dynvpn.com for the documentation.

Also make sure you follow @dynvpn on twitter and for specific question you can write to con...@dynvpn.com

let me know how it goes

cheers,

Nick

Hi Nick,

thank you for your instant answer.

I tried to install the new version, but unfortunately the snapd package is not support on Debian prior V9. I’m still struggling, because I cannot upgrade the client systems.

I also wrote a mail to cont...@dyn...

Thank you for further hints.

Kind regards,

Ferit
