Depends what you try to accomplish with this ie. sharing your payvpn account with your brother, or just sharing your internet connection with your brother(without being connected to payvpn)
well at the moment just tryng to share the connection, not payvpn. I'm using analogx proxy cause it is simply the easiest one out there and free. But he can't see the server. Any idea if payvpn would work from his pc through the proxy? Or would ICS be a better option?
If you use your pc as the gateway(point of sharing the internet) and connect to payvpn, anyone connecting to you will not be able to access international bandwidth as its solely routed to your specific pc only.
You need a NAT/ICS service runnning, windows internet sharing would be the easiest to share the connection and pretty straight forward to configure.
