Set up a VPN to play online poker remotely

I am looking for assistance in setting up a Windows or Linux PC at my home with a VPN server running on it. The PC will be provided and any OS can be installed on it. For VPN software, OpenVPN or other software can be used. I would like that computer to be on a seperate network from my home LAN, using another segment or VLAN. (The router is an ASUS RT-N66U so it could be done using a guest wifi network, or a virtual server.) I will then be connecting from a remote laptop using windows VPN or other VPN software and running a variety of online poker software (which connects over a variety of ports). The key is that the poker software only sees my home IP address and not my remote address. If the connection drops, I need software in place to block any direct communication with the poker server. Please contact me if you have any questions.
