How can I get this to work?

Hours of configuring - and no result. Is that possible at all?

P.S. UDP broadcasts are needed by old games for LAN play.

Are you using TAP devices?

To communicate by broadcast, all participants need to be in the same broadcast domain.

This requires bridging.

UDP Broadcasts are not forwarded to another interface then the main one. U are fine using UDP as protocol for OpenVPN. TCP would create to much traffic for playing games.

For finding games using openvpn i wrote a tool that clones udp broadcasts from the main interface to the other existing ones.

That makes you find most LAN-Games. Make sure your IP-Range of the VPN is set to some cause some games restrict hosts in LAN from different IPs.

I just released a stable version of the tool we are using. i you still need something to solve you problem check out link this link.

Make sure that the "client-to-client" option is turned on in the server config.

Also, you probably want to be running in bridged mode, not routed.

You may also want to configure OpenVPN to transmit over TCP instead of UDP.
