The new acls are a try to solve this output from the ASDM Logging:
443 Deny TCP (no connection) from 172.20.100.1/50142 to 172.20.0.1/443 flags FIN ACK on interface inside
Update:
I have remove the acls so that only "Lower Interface" rule is working
It seems that the connection to the DNS Server is established but than theconnection is closed with "Teardown" befor the information is transmittet.
All packets are translatet but is not working
