VIRTUAL DNS POLICY
« on: July 28, 2010, 04:17:08 PM »
Hi guys,
I need to create a rule that permit to forward a specific resolution to an external dns and the others to my internal.

For my internal users "ns.abc.com" to be resolved by dns.abc.com that is a public dns.
The other *.abc.com need to be resolved by my internal dns.
Is it possible??? How can do it? I've tried to create a dns policy but I can't find anything matching my will
Thanks a lot,
L.

Ozzy,

Sounds like dns doctoring which is common in cisco.  It's often helpful when you're hitting a server that's located on your local network using it's publicly nat'ed IP.  Cisco doesn't let you do that.  Traffic generated from LAN to hit the WAN interface translated back to LAN IP is a no no.. But I digress.

I don't know of a way to doctor dns on the Netscaler, or honestly a reason to do so.  Why are you doing this?  Perhaps there is a different way of accomplishing the same goal.
