I want to setup ISA Server with 3 network cards. One will be connected to the internal network, where all client workstations and corporate file/mail servers are. Two other network cards will be connected to two independent external networks; each external network has it's own connection to the Internet (to different ISP). I do have some unix/nt servers on both external networks - www, SMTP, etc. I want ISA server to route packets between those two external networks. In the same time I need highest level of protection for the internal network. So, the question: is it possible? anybody has experience with this kind of configuration? Do I need to configure specific packet filters to allow traffic between external networks? Thank you in advance.
