VIP address issues

Hi Gilles

Could you please help with the following?

If I have defined 2 VIP addresses and each of the VIP address has the same set of real servers then will there be a problem. This is specific to DNS servers.

Your help would be of great help

Thank you

Regards

Re: VIP address issues

There might be an issue.

For UDP traffic you have to configure a group to nat the server response back into the vip address.

If the servers are the same for both vip, on the way back to the client the CSS will not know which vip address to use - a server can only be in one group at a time.

A solution could be to do client nat. This might force the CSS to remember the vip address on the way back. Not sure as I did not try it.

Gilles.
