GTM DNS Response

I have a GTM behind a firewall. When I do an nslookup from the internet; DNS request times out.

 

I get the following response from a tcpdump;

 

[root@GTM-01:Active] config tcpdump -ni vlanx udp port 53

 

 

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

 

 

listening on vlanx, link-type EN10MB (Ethernet), capture size 108 bytes

 

 

00:50:28.189377 IP 1.1.1.1.23570 > 2.2.2.2.domain: 9+ A? server.wip.test.com.home. (42)

 

 

00:50:28.190537 IP 2.2.2.2.domain > 1.1.1.1.23570: 9 Refused- 0/0/0 (42)

 

 

00:50:30.188304 IP 1.1.1.1.23571 > 2.2.2.2.domain: 10+ A? server.wip.test.com. (37)

 

 

00:50:30.189068 IP 2.2.2.2.domain > 1.1.1.1.23571: 10*- 1/0/0 A 2.2.2.21 (53)

 

-------------------------------------------------------------------------------------------------------------------------

 

2.2.2.21 is the virtual server IP address the wideip resolves to. Not sure what the "refused" on the second line means.

 

If I use a web browser to the wide ip server.wip.test.com i get Error 105 (net:: ERR_NAME_NOT_RESOLVED): unable to resolve the server's DNS address.

 

Note: Listener is configured to the floating self ip

 

Can anyone shed more light on why the GTM isn't responding to the dns queries?
