From client side i get ip 10.8.0.2
On server i get 10.8.0.2

Ipforwarding is turned on in regedit

Thanks for reply, but unfortunately it doesnt work on my other server in different place that runs on ws 2012 r2. So i expect problem somewhere else.
Is the config 100% correct?

So now I am able to ping te server, but cannot acces internet. Ping 8.8.8.8 not responding. Any ideas?

I met the same problem,I tried many times when I setup openvpn server on windows server 2012r2 or 2016 ,it didn't work, but when I turned to windows server 2019 and setup in the same way, it worked well.

So the issues must come from the differences between these windows versions!

I also captured the ip packet to find reason,the result told me that TAP-windows adapter is unable to communicate with Ethernet adapter!

but I don't know why and I don't know how to solve,could anyone help me(windows is too troublesome!)
