heres my situation. i have 2 network adapters connected to 2 networks. is there a way to prioritize it so that certain programs or ports will only be used with one adapter or the other? i did set it so the windows firewall will allow network access to a certain program if the network is of the public profile, but deny it if its the private profile. both connections are simultaneously enabled. but now programs that are set to acces the private network cant connect because the public one seems to be the one thats handling all the traffic. so to clarify a little, i need both networks connected simultaneously but keep the traffic from program A confined completely to the adapter from the private network and program B to be completely confined to the public network.

Hi, Thank you for the post. Please understand that only one firewall profile may be active on the computer at any one time. Profiles are applied in the following order: public, private, and domain. Profile order is applied as follows: 1.If all interfaces are authenticated to the domain controller for the domain of which the computer is a member, the domain profile is applied.2.If all interfaces are either authenticated to the domain controller or are connected to networks that are classified as private network locations, the private profile is applied.3.Otherwise, the public profile is applied. For more information about Windows Firewall in Windows Vista, please refer to the following articles: A Windows Vista-based computer that is connected to a domain uses the public profile or the private profile for the Windows Firewall policy instead of the domain profilehttp://support.microsoft.com/kb/938756 Windows Firewall Profileshttp://msdn2.microsoft.com/en-us/library/bb736287.aspx Hope the information is helpful.

yes i realize that. using profiles didnt accomplish what i was trying to do so i was asking if there is some way to do it. i need to set it up so i can have both nics active but the traffic from one program completely confined to one nic and the traffic from another program confined to the other nic.

Hi, Thank you for your clarification. Please understand that a certain application would choose to bind to all adapters or one certain adapter by itself. This is determined by how the application was written. On the platform side, however, we have are unable to limit the application to go through a particular adapter. Some method such as firewall or IPSec can block the application's traffic on one certain network, but it would not make the application choose another adapter As a result, whether the application would choose one network or not totally depends on the application itself. If the application is unable to choose the network, then platform could not force the application to choose one certain network. Thank you for your understanding.
