No internet connection when connecting to VPN

Postby ohadb2 » Tue Apr 18, 2017 9:40 am

Hi,

I installed VPN Server on my Windows computer.
When I tried to connect from my MAC computer I got this error:
Image

So I tried to add this line to the server config file:
push "redirect-gateway local def1"
(I set local because the windows connect via Wi-Fi, I tried to remove it but I still got the same issue).

But not when I connecting to the VPN I got this error:
Image

I tried to add google dns manually but still had the same problem.

My server config file:

Code: Select all

port 1194

Googling "ping: sendto: No buffer space available"
suggests there is something wrong with your network.

I can not see any specific Openvpn problems in your client log file.

Hmm, that's an interesting issue, I also can't see any specific OpenVpn issues. I will take another look later today.
