bonnybros i have been facing a strange problem in my openvpn setup. It runs perfectly when the Windows server 2012 R2 is up. But the issue happens when server restarts. Or lets say if i go and restart the service (2nd time). It uses the virtual IP (10.8.0.1) and the configuration is exactly similar to what is their in OpenVPN community. It automatically changes to a different IP starts with 169.x.x.x and in the description it says Auto Configuration enabled. When this change happens i wont be able to ping using the server IP 10.8.0.1, of course because the IP is different now. In that case i need to set the IP manually as 10.8.0.1 and gateway as 10.8.0.2 to make it work again. Has anybody come across a strange situation like this? I am really pissed off due to this. Is there anyway to stop this happening again?
bonnybros TinCanTech wrote Sounds like a dhcp problem .. Thanks for replying. DHCP is Auto & handling by Windows 2012 server. Did i miss something else to configure in OpenVPN?
bonnybros I could solve it by adding these details. proto udp4 Specifies to use IPv4 on the UDP protocol for better clarity to system and prevents an error in the server's OpenVPN log which states "Could not determine IPv4/IPv6 protocol. Using AF_INET6" ip-win32 netsh Allows a manual configuration of the IP during OpenVPN server startup Tested it many times and i couldnt reproduce the same issue. Seems i got it solved. Thanks!
