iRule Possibilities for LDNS from a client workstation

Hi Philip, Unfortunately if the GTM sees the current DNS servers as the LDNS source so will the iRule on it. DNS doesn't carry special information regarding the client who requested so you can't pick that up within iRule either. However, you may be able to accomplish this by asking to turn off recursive for a specific domains. I do remember that with Windows DNS it's a global settings so it's basically an ON or OFF switch accross the board. However, I do remember that you can do this in BIND.

I hope this helps,
