Setting up Win7 PC as PPTP VPN Proxy Server for use with iPhone

Hey guys,

I've been digging through forums and sites for the past couple months now trying to find a way to help me turn my home PC into a proxy server so I may use Pandora Radio on my iPhone over public WIFI at work. Recently our corporate offices upgraded their network and in turn added a firewall which blocks many common external sites, one of which included Pandora.

I have found a temporary workaround by way of using Hotspot Shield's free VPN services, but I would like to create my own proxy server at home instead so I can avoid the constant timeouts/disconnects involved with the free service.

So far I've set up my PC to use a static IP on the network, and forwarded port 1723 to that address. I've also enabled incoming connections under adapter settings, but it just seems like I'm missing something big here. I am unable to make a connection to my home PC from my iPhone over WAN, and even if I was able to I'm not sure how to enable internet connection sharing over that connection.

Is what I would like to do at all possible or feasible? Any help would be greatly appreciated!

Is there no one with any tips or the knowledge of any programs out there to simplify what I'm trying to do?

OK, rather than leave a thread hanging... I thought I'd respond to this incase someone else out there was searching on this. I found this thread and was left with a wanting need to solve it... so here it is:
1. Setup PPTP on your windows 7 machine. There are various guides out there, I used this one as it includes a dialogue on forwarding the port on your router: Setup a VPN – PPTP Host On Your Home Windows 7 PC [How-To]

One thing it doesn't cover. When you set the Incoming IP properties, do not allow "assign IP addresses automatically" instead set a range. This caused me hours of troubleshooting to workout.

2. Setup your iPhone for PPTP. Go to (and this is on your iPhone) settings -> general -> network -> (scroll down) VPN -> Add VPN Configuration. Then select PPTP, put a useful description, server (your IP address for your router accessible from the internet, use dyndns or other to make it easy), account is your username on the Windows 7 machine, password is the password for this account (you did set one up right).

The last key is Proxy. This can enable you to route all VPN traffic through your PC. This is the question the original poster is asking for. Try Manual or Auto and see which one works for you.

If you can't connect from the WIFI you are on. Just make sure the port is open (1723).
