iquery source IP on BIG IP DNS
Hi
What is the source IP used by BIG IP DNS ( management IP or listerner IP ) to establish an iquery session with LTM.
Need clarity on what source/destination IP and port combinations should be explicity allowed on firewall !
Thanks

As far as I know, the Big-IP will use a non-floating Self-IP given by the default routing table.
You can discover the source address by using the ip command. In the following example the self ip 10.10.10.254 will be the source for the iquery-target 10.2.2.2.
[admin@bigip-dns:Active:Standalone] ~ # ip route get 10.2.2.2 10.2.2.2 via 10.10.10.1 dev arm0 src 10.10.10.254 cache
