Help with pfSense VPN proxy setup

[Aneurysm]

Hi,

I was wondering if someone might be able to help me with some setup of pfSense on an Alix2D2.

I have an Alix which I wish to use on my local LAN as a VPN proxy device. I would like to be able to point any other device on my network at the Alix as a proxy and the Alix would then route those connections via OpenVPN to my VPN providers. I have OpenVPN configured, but I am not sure how to go about creating a proxy server to redirect requests through the VPN tunnel. Can anyone give me any advice to assist with this setup?

I currently have the Alix plugged into the LAN via one of the NICs the other NIC is unused.

Thanks in advance,
