A Windows Server 2008 R2 (SP1) server is configured with the following IPs (in order):
x.x.x.50 x.x.x.40 x.x.x.41 x.x.x.42
For DNS requests, it appears to be using
x.x.x.40 as its outbound IP, but when an application makes a request it uses
x.x.x.50. This seems unpredictable and we're trying to create routing and firewall rules in our switches and firewalls, but aren't sure how it's determined which IP is used in what context.
Any insight would be greatly appreciated.
