Hi Jason, What specific questions or issues do you have? The ISA firewall is a network firewall in the same way as checkpoint or astaro (I don't really consider the PIX is firewall, but a rather a flexible packet filtering router). So, just use the same principles of firewall and network design you would apply to a Checkpoint box to the ISA firewall. If you have specific questions, ask!

This is my team's first experience implementing a proxy based firewall...we are very familiar with Cisco and other networking based gear. We will continue to use our current equipment in tandem with ISA 2004. Our desire is to use ISA for outbound Internet access as we currently have a very robust and segregated network for inbound traffic. We will be bringing in consultants to help us however we would like to work on some things beforehand. Can anyone point me to a good resource for implementing ISA 2004 for this size of a network to include authentication, filtering with N2H2, while working in a dual firewall scenario. Thanks in advance...
