I've tried to configure VPN in Lion (both L2TP and PPTP), but it never connected successfully.

The same VPN works fine in Windows 7 and the iPad and other mobile devices, so I think it could be a problem with Lion.

Did I miss something when trying to configure the VPN?

My system is Mac OS X Lion 10.7.2 (11C74).


Below is the log file.

Have you checked the firewall on your Mac? Maybe it prevents the needed communication between the VPN device and your computer. – SAE Jan 12 '12 at 16:28
    
I regularly connect to multiple VPN's using Lion. I would make sure you have the authentication settings correct. – Stu Wilson Jan 12 '12 at 21:32
    
thanks for your answer, the firewall is not open and allow all connections in. I guess it might be line problem? I'm in china, using ADSL, using a wireless route and dial through PPPOE. Is it possible the ppp program on lion is not compatible with the PPPOE? or need I modify some configuration of the ppp prpgram? However, the vpn works fine on my win7 PC and ipad(using the same net topology), so it should not the vpn's provider's problem. – situch Jan 13 '12 at 1:20
