Airport Extreme N Basestation 7.2.1 still does not fix SonicWall VPN issue

Six months ago I bought an Airport Extreme N Basestation. The VPN has never worked with Sonicwall VPN client.

Now, six months later, firmware 7.2.1 is out and the VPN is still broken.

How patient should one be, waiting for Apple to support standards?

Linksys works, why can’t Apple?
