Hi Dhanikonda,

Access list MZ_access_in which is defined in your firewall is blocking the traffic. rule is not permitted..... so please allow the specific flow in the ACL to allow the specific flows....

access-list MZ_access_in line 1 extended permit udp host 111.93.252.6 eq 53

!

add your lan segment subnet in the acl & apply the above access-list and try.... it will work... it will start resolving the hostnames & url's....
