We have created an ACL to allow TCP and UDP port 53 to/from DMZ and Inside Network. When we use packet-tracer tool through ASDM to verify the connectivity from DMZ to inside interface UDP packet gets dropped.
When we test the same port_53 using TCP it works perfectly fine.
We are getting error (inspect-dns-invalid-pak)DNS Inspect Invalid Packet.
Kindly Help us troubleshoot the problem.
