Cisco CSR1000v 16.06.04 self zone DNS ?

signup4432
Level 1
Level 1

Having an issue with the router being able to do DNS queries. Here's my config (condensed). Can't seem to get it to work. If I remove the self zone works fine and I just cant seem to figure out what I'm doing wrong so the router can route DNS. I did add an external IP NAME-SERVER.

class-map type inspect match-any All_Protocols
 match protocol tcp
 match protocol udp
 match protocol icmp

class-map type inspect match-any self-to-out
 match access-group 111

class-map type inspect match-any out-to-self
 match access-group 112

policy-map type inspect self-to-out
 class type inspect self-to-out
 pass
 class class-default
 drop log

policy-map type inspect out-to-self
 class type inspect out-to-self
 pass
 class class-default
 drop log
