Hello all, Current configuration Internet --Isa Integrated1 -- Our LAN HQ is planning following configuration Internet-- border manager --Intranet (mail etc) -- Isa1-- Our LAN ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ They call this the backbone And this is what I want Internet-- border manager --Intranet (mail etc) -- Isa1-- Our LAN -- IsaIntegrated2 -- internet I want to keep our current configuration, most of the traffic goes thru ISA2, but if an intranet page is requested it should be handled by ISA1 for all users. And a special group uses only ISA1 (they have a roaming profile) for all traffic. Some users have multiple mail addresses. Some mail should be fetched from the internet and 1 mail address should be fetched from the backbone. The problem is that it is still in development (backbone is not implanted in all branches) so I can not test it at the moment. But I would like to think ahead and like to hear what are you're thoughts on this subject. What do I need ? Thanks for thinking along, Paul
