hi all, We are now in process of planning new Exchange 2010 organization. We have a Cisco Firewall in our network, I want to use Cisco firewall for exchange publishing. Is there a lot of benefits to buy TMG server for Exchange publishing? Can you give me some links where exchange publishing topology is discussed?

Hi The cisco fw can't authorize AFAIK, the ISA/TMG is a reversed proxy and the clients/devices can authenticate direct to TMG , so it will add another layer of security For more info about isa server, have a look at the link below http://www.isaserver.org/Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog
