DNS request behind content switch: troubleshooting

Unanswered Question
Mar 20th, 2007

Hi, sometimes we experience problems resolving a dns name behind a content switch. The problem solves himself after 5 minutes or something like that. We see the dns request on the dns servers subnet. It looks like the is a problem when the packet returns. I'm thinking of a nat problem. How can i best troubleshoot this?

is the traffic nated by the CSS or simply routed ?

Would be good to have your config so we can better understand the situation.

Is the response from the server delayed before it gets to the CSS ?

Can we see a sniffer trace captured in front of the CSS [on the side CSS - DNS_server].

Can i e-mail you the config file? I will also e-mail as soon as possible a network capture in front of the CSS. Where can i e-mail it? For the moment dns is working so i will have to wait for network capture untill it fails again.

Kind regards,
