(both Windows and Linux) won't cut it. You maybe able to connect to pia servers but due https://www.privateinternetaccess.com/forum/discussion/3481/quick-guide-howto-ipsec-l2tp-on-windows-7-from-china-nat-t-error-809-error-789 to deep packet filtering you will still not be able to load all those evil websites like youtube, google, facebook, etc. Also the part of this guide about NAT-T maybe helpful to other Windows 7 users behind NAT, usually a home router for broadband/cable.The solution is IPSec/L2TP but gettting it to work on Windows 7 was a pain, but like anything, error 789 easy when you know how.First you need to follow this guide from pia.https://www.privateinternetaccess.com/pages/client-support/#windows_l2tp_ipsecThen there is one important step they miss out. By default Windows 7 NAT-T is not enabled so a little registry hack is required. (I got error 809 when I tried to connect without this reg edit). Log on to the Windows 7 client computer as a user who l2tp ipsec windows is a member of the Administrators group.ClickStart, point toAll Programs, clickAccessories, clickRun, typeregedit, and then clickOK. If theUser Account Controldialog box is displayed on the screen and prompts you to elevate your administrator token, clickContinue.Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgentOn theEditmenu, point toNew, and then clickDWORD (32-bit) Value.TypeAssumeUDPEncapsulationContextOnSendRule, and then press ENTER.Right-clickAssumeUDPEncapsulationContextOnSendRule, and then clickModify.In theValue Databox, type '2'ClickOK, and then exit Registry Editor.Restart the computer.This should solve the NAT-T error 809 issue for Windows 7 users.For people like me in China there is an extra complication. The Great FireWall likes to play tricks with dns so pia server names will often not resolve. You need the I.P. So you can either ask support for the I.P for the server you need or do as I did and do a dns lookup from a web site such as dnsstuff.com (If I used a server name rather than I.P I would get an error 789)Then you should have a vpn connection to pia! Now if we could just speed things up a little that would be great!And lastly, credit
