EazyVPN on ASA5505 and split-dns

Unanswered Question

We have an ASA 5505 (Software Version 8.2(1)) configured as an Easy VPN Client, the other side (3000 Conncentrator) pushes a dns-server and some split domains onto the ASA.

Sadly split-dns is not working correctly, i.e it looks like our ASA sends all dns traffic down the tunnel.

Any ideas how to get rid of this behaviour?
