OpenVPN: why is the server not pinging?

Question

VPN

Much has been written about this on the Internet, but I have not solved my problem.
I have a vpn server on ubuntuserver installed and configured, a client on windows 8 - it connects without problems. However, the server does not ping. The firewall is disabled, the antivirus is generally demolished. I'm already lost in thought.
Client config

client
dev tun
proto udp
remote ***********
port 1194
resolv-retry infinite
persist-key
persist-tun
ca ca.crt
cert kirill.crt
key kirill.key

Answer 1

There was no such garbage on win2003 and xp clients and server. On win7 I don't know why, but you need to
1. restart the server as administrator
2. run the client as administrator
