I'm not a networking expert, but a software engineer and have some tertiary experience with networking protocols, so I may be wrong and couldn't tell you for sure, but my guess would be that since the main difference between UDP and TCP protocols are that UDP is fire-and-forget and TCP requires a "handshake" with more information being passed back and forth between ends of the connection. On the other hand, UDP is more efficient once the connection is established. If you experience problems with VoIP video/audio conversations when connected to the VPN through a TCP port, a typical case for which a difference may be visible (VoIP over TCP - for example UDP over TCP - is clearly inferior to VoIP over UDP because TCP implements ARQ I recently upgrade my router to DD-WRT with the VPN option. It serves as the main router for my network and gateway to the internet. The OpenVPN server runs on it.
