I need to set up a standalone array for a TMG2010 enterprise server. While i understand the process of adding another server intho the array - http://technet.microsoft.com/en-gb/library/dd440981.aspx
i am not clear about how the network failover is going to work, i.e. do i need a virtual ip address or any other particular firewall rules set up?
I also need to set up resiliency for a Windows 2008 ADFS server. What would be the recommended way of doing this and, again, how will the network fail-over work?
Both servers are part of an Office 365 post-migration configuration (if that makes a difference)
Any help would be greatly appreciated.
