webserver (client) unable to reach DNS
we have an issue where web servers (vlan40) are unable to reach DNS. for servers F5 is the gateway. Can see DNS traffic coming in but no DNS response. Fw which is next hop is unable to see DNS traffic.
Checked everything - portchannel (vlan40, int 1.3) is up - we have wildcard performance layer4 VS configured enabled on vlan40 configured - able to reach DNS from load balancer - Can see DNS response coming in for hosts in another vlan.
Please guide what should be next troubleshooting steps Thanks
