If you have both Windows and *nix clients in your OpenVPN implementation and need them to be able to communicate with each other (‘client-to’client’ option in the server configuration file), you may face the problem on Windows, while using the stable version of OpenVPN GUI<\/a>. It’s based on 2.0 OpenVPN, which doesn’t have the ability to handle client connection with \/24 subnet mask, and we strongly need it.
\nIn such a case use the development version of OpenVPN GUI. For this moment (June 6, 2013) it is OpenVPN 2.1_beta7 & OpenVPN GUI 1.0.3<\/a>. The trick is that OpenVPN supports ‘topology xxx’ directive starting from the 2.1 version, and the development package (as for today) for Windows is based on it.
\nYour Windows client’s<\/em> configuration file should be similar to this:
\n
\nclient
\ndev tun
\nproto udp
\nremote IP.ADD.RE.SS 1194
\ntopology subnet
\nnobind
\npersist-key
\npersist-tun
\n;
\nca \"c:\\\\program files\\\\openvpn\\\\ca.crt\"
\ncert \"c:\\\\program files\\\\openvpn\\\\client5.crt\"
\nkey \"c:\\\\program files\\\\openvpn\\\\client5.key\"
\n;
\ncomp-lzo
\nverb 3

UPDATE: as for now (January 30, 2018) Windows version is available from other location: https:\/\/openvpn.net\/index.php\/open-source\/downloads.html<\/a>
