VPN usage and security

[Renk]

I have a question. Suppose (it's of course only an hypothesis) I use some P2P client through a vpn (e.g. relakks). Suppose that some evil anti p2p people are using a spy mod version of the same P2P client, through the same relakks.

Could they see my real IP or whatever else ??

Only the Relakks server can know your real IP. The most other users on the same service could manage to see is your "relakksed" address. But just in case disable the "File and Printer Sharing" TCP/IP service at the VPN connection's properties as the Relakks FAQ strongly recommends.

Also you can just use a semi anonymous masking for your VPN IP whenever you use a p2p client (either BT Clients or just normal p2p clients),that would be too useful in order to stay a bit shadowed,check it here.

Thanks for linking to my tut, Aurion

Yes, it's of course possible to combine my method with VPN to gain even more anonymity, but Relakks is a fully featured service that'll encrypt all your IP traffic, so it gives you more anonymity than what you can gain with Ultrasurf/Freegate.

Although some trackers have banned Relakks' IPs, for example What.cd. What's IP ban is indeed possible to bypass with my method - but if you chain yourself behind too many proxies you may end up losing connectability (NAT problem, red light in Azureus).
