Exchange 2010 CAS array and TMG

We have 2 cas servers with casarray and 2 mailbox servers with 1 fsw pointing to one cas/ht
We are also using hardware loadbalancers.

If we wanted to deply TMG 2010, should we get 2 TMG servers or 1 sufficient.

Also how should it be in order:
Internet, TMG 2010, hardware loadbalancers, casarry?
Internet, hardware loadbalancers, TMG 2010, casarray?

Thanks
Jaz

Hello,

If you want HA on your TMG servers, setup two TMG servers in an array. You don't use hardware load balancers in front of TMG. For details on how to set this up, see here - http://www.isaserver.org/tutorials/TMG-Enterprise-Arrays-Explained.html

Your order would typically be:

Internet - external firewall - TMG Array - internal firewall - hardware load balancers - CAS array
