Connects to AirVPN, but Internet stops working (OS X 10.7)

[Guest]

Some relevant info:

- OS X 10.7 (Firewall disabled)

- Tunnelblick 3.2.8

- OpenVPN 2.2.1

- Linksys e4200 Router

- When connected to AirVPN my DNS shows "10.4.0.1"

Problem:

I can connect to AirVPN, but once I do my internet traffic stops working (Browsers, Dropbox no longer connects).

Used to work perfectly for months, but this has recently become a problem I cannot fix.

Log:

Hello!

Apparently Tunnelblick/OpenVPN receives the OpenVPN server push but does not execute the route commands.

Please see here for some considerations:

http://code.google.com/p/tunnelblick/wiki/cConnectedBut

If everything else fails, please try to uninstall Tunnelblick and upgrade to Tunnelblick 3.3beta21:

Kind regards
