VPN only specific ports or programs

[Californ1a]

So my current problem is that I'm in university housing, and using their network, which tends to block connections to a lot of game servers, especially player-hosted servers where the host may not necessarily be portforwarded and is relying on open nat. I'm on Windows 10 x64, and have been using the free version of VyprVPN for a little while, only issue is that on the free accounts, there is a 500MB limit, which means I can't watch youtube or do anything else while playing a game since all the extra traffic will be going through the VPN. I'm wondering if there is a way to possibly limit the VPN to only traffic on specific ports/programs, or if there is a better free vpn (no time/data limits). VyprVPN allows me to input additional OpenVPN parameters in the advanced settings, but I've no clue if any of that is even helpful. Specifically, I'd want port 45671 and Elite: Dangerous's p2p matchmaking servers to work (can't play E:D at all right now without a vpn, just get disconnected 2min after joining ).
