Hi,
This is a problem that I can't seem to resolve, and cisco TAC couldn't help me with it. Everytime I browse the web, my DNS lookups seem to be delayed and can sometimes take up to a minute before the lookup is done and the web page returns. This is on an ASA5505 and I can put linux and os x boxes behind it and they all have the same problem.
Anyone have any ideas on how find this problem? Any help much appreciated.
