I want to setup VPN server and route (based on my routing algorithm) all traffic through different proxy servers. Let's say I have one host, with many users, connected to my VPN. I want to route all traffic from/to user1@myhost through proxy1, user2@myhost via proxy2 and so on.
That's how it should look like:
main host (user1, user2) <--VPN--> proxy server <--proxies (proxy1 for user1, ect)--> internet
The goal is to give each main host user different IP address.
