Module:OpenVPN
There are error message after apply configuration OpenVPN 
Ehi Ya,
Please, can you add more details? Logs, configurations and so on…? Unfortunately a screenshot like this isn’t enough
Hi Ale , hi Ya
i’ve faced t the same issue on 7 rc2 enterprise ,in my case was a misconfiguration of the routed mode class that was the same of a green subnet, solved just by modifying the routed mode subnet.
hope this helps

Hi Ya,
I can confirm @fmenegoli experience:
If network is set to green IPs (in my case 192.168.0.0) an error 500 appears.
If you set the network to i.e. 10.10.0.0 it should work.
@giacomo @davidep can this field be ckecked like: if network is in green/red => message “Please choose a different networkrange.”? That would avoid missunderstanding.

Yes, we can add a validator.
I added it to RC4 release plan: https://github.com/NethServer/dev/projects/2#card-1107702

Validator was the word I was looking for, but didn’t find it. Thank you Giacomo.
I think I should validate my vocabulary by more learning with my kids… 
Validator looks like a Decepticon… 
Let’s go validate them all!!
I’m having the same problem! Error 500! I tried on another network and even on different installations, but from the same error
