hi I have a router 2900 and I have configured it as DNS SERVER but the host devices send the dns query and do not receive the response dns, when I ping the router 2900 domain to ip it is successful I have configured access-list x.x.x.x x.x.x.x.x any any eq 53 | x.x.x.x x.x.x.x any eq 53 any | tcp, udp x.x.x.x x.x.x.x any
