AltostratusSimple DNS query without virtual servers
Hi,
I'm trying to explore DNS features of BIG-IP and have a very simple set-up. However, when using nslookup/dig I receive a query refused error.
Setup: listener on udp port 53, example ip address: 10.10.10.10
Wide-IP: application.test.local
There are no virtual servers or pools assigned to this wide-ip but one iRule:
when DNS_REQUEST {
host 10.20.20.20
}
I think this is the simplest set-up you could have and expect a DNS response, but like I said I am not receiving any from dig application.test.local @<big-ip-dns-listener-address>
Is there something fundamental I am missing?

Zchriss, out if interest where is the irule assigned? The wideip or listener object? It should be assigned to wideip due to the default processing of DNS when a request matches a wideip.
