Hi,
I've setup a CSS to load balance between 2 servers using layer3 balancing, but I discovered that when requesting a dns lookup (the two servers are acting as primary dns servers), I get the following response from a terminal nslookup:-
';; reply from unexpected source: 192.168.0.120#53, expected 192.168.0.101#53' Whereas 192.168.0.120 is the actual server IP and 192.168.0.101 is the VIP. Is this related to the dns server itself or the CSS?

Trevor,
This is due to the way the CSS handles UDP traffic. There are a couple of options for dealing with DNS, which you can find more information about here:
